abbreviation

A shortened form of a word or phrase used for brevity in place of the whole, consisting of the first letter, or the first few letters, followed by a period (full stop), for example, assoc. for association or P.O. for post office. Some terms have more than one abbreviation (v. or vol. for volume). Also used as an umbrella term for any shortened form of a word or phrase not an acronyminitialism, or contraction, for example, the postal code CT for Connecticut. The rules governing the use of abbreviations in library catalog entries are given in Appendix B of AACR2. Abbreviated abbr. In medieval manuscripts, abbreviations were often used to save time and space, and readers of the time would have been familiar with them. Michelle Brown notes in Understanding Illuminated Manuscripts (Getty Museum/British Library, 1994) that Irish scribes relied on them extensively in copying pocket-size Gospel books used for study.

abridgment

A shortened version or edition of a written work that preserves the overall meaning and manner of presentation of the original but omits the less important passages of text and usually any illustrations, notes, and appendices. Often prepared by a person other than the original author or editor, an abridged edition is generally intended for readers unlikely to purchase the unabridged version because of its length, complexity, or price (exampleThe New Shorter Oxford English Dictionary). Also spelled abridgementAbbreviated abr. Synonymous with condensation. Compare with simplified editionSee alsoabstractbriefdigestepitomesummary, and synopsis.

abstract

A brief, objective representation of the essential content of a bookarticlespeechreportdissertationpatentstandard, or other work, presenting the main points in the same order as the original but having no independent literary value. A well-prepared abstract enables the reader to 1) quickly identify the basic content of the document, 2) determine its relevance to their interests, and 3) decide whether it is worth their time to read the entire document. An abstract can be informativeindicativecritical, or written from a particular point of view (slanted). Examples of the various types of abstracts can be seen in the Appendix of the ANSI/NISO Z39.14 Guidelines for Abstracts.

Length depends on the type of document abstracted and the intended use of the abstract. As a general rule, abstracts of long documents, such as monographs and theses, are limited to a single page (about 300 words); abstracts of papers, articles, and portions of monographs are no longer than 250 words; abstracts of notes and other brief communications are limited to 100 words; and abstracts of very short documents, such as editorials and letters to the editor, are about 30 words long. In a scholarly journal article, the abstract should appear on the first page, following the title and name(s) of author(s) and preceding the text. In a separately published document, the abstract should be placed between the title page and the text. In an entry in a printed indexing and abstracting service or bibliographic database, the abstract accompanies the citation. Because the abstract is a searchable field in most bibliographic databases, attention must be paid by the abstractor to the keywords included in it. Authorship of an abstract can be unattributed or indicated by name or initials. An author-supplied abstract is usually written by the author of the work abstracted. Compare with summarySee alsoabstracting journalauthor abstract, and structured abstract.

abstracting and indexing (A&I)

A category of database that provides bibliographic citations and abstracts of the literature of a discipline or subject area, as distinct from a retrieval service that provides information sources in full-text.

abstracting journal

journal that specializes in providing summaries (called abstracts) of articles and other documentpublished within the scope of a specific academic discipline or field of study (examplePeace Research Abstracts Journal). Synonymous with abstract journal. Compare with abstracting service.

abstracting service

A commercial indexing service that provides both a citation and a brief summary or abstract of the content of each document indexed (exampleInformation Science & Technology Abstracts). Numbered consecutively in order of addition, entries are issueserially in print, usually in monthly or quarterly supplements, or in a regularly updated bibliographic database available by subscription. Abstracting services can be comprehensive or selective within a specific academic discipline or subdiscipline. Compare with abstracting journal.

accession

To record in an accession list the addition of a bibliographic item to a library collection, whether acquired by purchase or exchange or as a gift. In automated libraries, the addition is usually recorded by enhancing a brief order record that is expanded in cataloging to become the full bibliographic record entered permanently in the catalog. Also refers to the material added. The process of making additions to a collection is known as accessions. The opposite of deaccession. Compare with acquisitionsSee alsoaccession number and accession record. In archives, the formal act of accepting and documenting the receipt of records taken into custody, part of the process of establishing physical and intellectual control over them. In the case of donated items, a deed of gift may be required to transfer legal title.

accession number

A unique number assigned to a bibliographic item in the order in which it is added to a library collection, recorded in an accession record maintained by the technical services department. Most libraries assign accession numbers in continuous numerical sequence, but some use a code system to indicate type of material and/or year of accession in addition to order of accession. See alsoLibrary of Congress Control Number and OCLC control number.

accompanying material

Related but physically distinct material issued with an item, for example, a floppy diskCD-ROMslide set, answer bookteacher's manualatlas, or portfolio of prints or plates, intended by the publisher to be used and stored with it, often in a pocket inside the cover or loose inside the container. In AACR2, the presence of accompanying material is indicated in the physical description area of the bibliographic recordSee alsodashed-on entry.

acquisitions

The process of selecting, ordering, and receiving materials for library or archival collections by purchase, exchange, or gift, which may include budgeting and negotiating with outside agencies, such as publishers, dealers, and vendors, to obtain resources to meet the needs of the institution's clientele in the most economical and expeditious manner.

Also refers to the department within a library responsible for selecting, ordering, and receiving new materials and for maintaining accurate records of such transactions, usually managed by an acquisitions librarian. In small libraries, the acquisitions librarian may also be responsible for collection development, but in most public and academic libraries, this responsibility is shared by all the librarians who have an active interest in collection building, usually on the basis of expertise and subject specialization. For a more detailed description of the responsibilities entailed in acquisitions, please see the entry by Liz Chapman in the International Encyclopedia of Information and Library Science (Routledge, 2003). Click here to connect to AcqWeb, an online resource for acquisitions and collection development librarians. Compare with accessionSee alsoAcquisitions Section.

Acquisitions Section (AS)

Created in 1991, AS is the section of the Association for Library Collections and Technical Services (ALCTS) within the American Library Association (ALA) charged with (1) promoting the effective acquisition of information resources in all formats, through purchase, lease, and other methods, in all types of institutions; (2) developing sound ethical, fiscal, and legal policies and procedures in acquisitions management, including relationships with suppliers; and (3) assessing and advancing awareness of the organization and role of the acquisitions function within the library and in relationships with other functional areas (purchasing, accounting, collection management, etc.). Click here to connect to the AS homepage.

added copy

copy of an item already owned by a library, added to the collection usually when demand warrants. Compare with duplicate.

added edition

added entry

A secondary entry, additional to the main entry, usually under a heading for a joint authorillustratortranslatorseries, or subject, by which an item is represented in a library catalog (AACR2). See alsoname-title added entry and tracings.

ad hoc

Latin for "to this," used to indicate that something was created or exists for the particular purpose in view at the moment. Also refers to something organized for a specific purpose, for example, an ad hoc committee elected or appointed to address a specific issue or handle an unanticipated contingency, usually dissolved once the need has been met.

adoption

An agreement that a specific textbook will be used for teaching purposes in a state-supported educational institution (school, college, or university). Government approval is required for textbook adoptions in the public schools in many states in the U.S. (see this example).

advance copy

copy of a book or other publication bound in advance of the normal press run to enable the publisher to check that all is in order before binding of the edition proceeds. Advance copies are also sent to booksellers, book club selection committees, and reviewers before the announced publication date, sometimes unbound or in a binding other than the publisher's binding, often with a review slip laid in. Copies sent unbound are known as advance sheets. Synonymous with early copy. Compare with reading copy and review copy.

advance on royalty

A non-refundable sum paid by the publisher to the author(s) of a new book prior to its publication against the royalties it is expected to earn, usually offered as an inducement to sign a book contract. When actual royalties exceed the advance, additional earnings are paid out according to the terms of the publisher's agreement. Synonymous with author's advanceSee alsounearned advance.

advance order

An order placed for a new book prior to its date of publication, usually in response to prepublication promotion. The number of copies ordered in advance may assist the publisher in determining the size of the first printing, the price, and how much to spend on advertising.

all published

note in the bibliographic record describing a publication originally proposed in more than one part or volume but never completed, usually because it was discontinued by the publisher. Similarly, a note describing all the issues of a periodical for which publication has ceased. In bookselling, a serially published work for which all issued parts are present.

alumni access

Provision of remote access to proprietary research databases to the graduates of an academic institution. A survey of 102 U.S. college and university libraries conducted in 2006 by Catherine Wells of Case Western University (C&RL News, July/August 2006) revealed that only 18 institutions offered database access to alumni. Dartmouth College began its service in 2002, making it one of the longest established programs. Some academic libraries provide alumni access as part of a suite of services offered via a specially-designed alumni portal. Of the major database vendors, only EBSCO and ProQuest currently offer alumni access to at least some of their databases for an additional fee.

analytical bibliography

The comparative and historical study of books as physical objects, including the methods and techniques of book production and their influence on texts. Synonymous with critical bibliography. Analytical bibliography has three main branches:

analytical entry

An entry in a library catalog for a part of a work (chapter in a book) or an entire work (storyplayessay, or poem) contained in an item, such as an anthology or collection, for which a comprehensive entry is also made. Analytical entries are made under the authortitle, and subject of the part and include a reference to the title of the work containing the part. Because preparation of analytical entries is time-consuming, the level of bibliographic description provided in a catalog depends on the administrative policy of the library and its assessment of local needs. Synonymous with analyticsSee alsoanalytical note.

annual review

serial publication that surveys the most important works of original research and creative thought published in a specific discipline or subdiscipline during a given calendar year (exampleAnnual Review of Information Science and Technology). In most academic librariesannual reviews are placed on continuation orderSee alsoreview journal.

APA style

guide for typing research papers in the social sciences, developed by the American Psychological Association, which includes the proper format for typing notes and bibliographic citations. APA style is described fully in the most recent edition of the Publication Manual of the American Psychological Associationavailable in the reference section of most academic librariesClick here to connect to the Yahoo! list of APA style guides. Compare with MLA styleSee alsoelectronic style.

appendix

A part of a written work, not essential to the completeness of the text, containing complementary information such as statistical tables or explanatory material too long to be included in the text or in footnotes or endnotes (click here to see an example in the CIA World Factbook). An appendix differs from an addendum in having been planned in advance as an integral part of the publication, rather than conceived after typesetting occurs. Appendices usually appear in the back matter, following the text and preceding the notes, glossarybibliography, and indexAbbreviated app.

archival copy

copy of a document specifically created or designated for archival storage by the company, government, organization, or institution that wishes to preserve it, usually for legal, evidential, or historical purposes, for example, a copy of an academic thesis or dissertation specifically designated for preservation in the archives of the college or university to which it was submitted. See alsoarchival quality and preservation photocopy.

archival database

An organized collection of records in digital format, containing information to be retained for an indefinite period of time, usually for future reference, for example, the messages received and distributed by an e-mail discussion list or the reference questions received by an digital reference service, including the answers provided. JSTOR is an example of an archival journal database.

archival journal

journal published mainly for archival purposes, as opposed to one intended for distribution to retailers and individual subscribers, usually priced for the library market with little or no attempt to market it to a wider audience.

archive

The building, facility, or area that houses an archival collection (the term repository is preferred by most archivists). Also, to place documents in storage, usually to preserve them as a historical, informational, legal, or evidential record, permanently or for a finite or indefinite period of time. See alsodigital archive.

area study

publication that provides factual information about a specific region of the world (Africa, Asia, Europe, Latin America, the Middle East, etc.), including a description of its physical and social geography, economy, history, governments, and cultures, and that may also contain pertinent statistical and directory information. Area studies are often published serially (exampleThe Far East and Australia in the Regional Surveys of the World series, published annually by Europa). Compare with country study.

article

A self-contained nonfiction prose composition on a fairly narrow topic or subject, written by one or more authors and published under a separate title in a collection or periodical containing other works of the same form. The length of a periodical article is often a clue to the type of publication--magazine articles are generally less than five pages long; scholarly journal articles, longer than five pages. Also, journal articles often include a brief abstract of the content (click here to see an example). Periodical articles are indexed, usually by author and subject, in periodical indexes and abstracting services, known as bibliographic databases when available electronically. Compare with columneditorial, and essaySee alsocover story and feature.

Also refers to the words aan, or the, or their equivalent in another language, used as adjectives preceding a noun, the being the definite article, and a and an indefinite articles. In library filing, an initial article is ignored at the beginning of a heading. An initial article is also ignored in a title search of an online catalog or bibliographic database.

ASCII

An acronym for American Standard Code for Information Interchange (pronounced "askee"), the binary code built into most minicomputers and all personal computers to represent in digital format the uppercase and lowercase letters of the Latin scriptnumerals, and special characters. Each ASCII character consists of seven information bits and one parity bit for error checking.

Designed to facilitate information exchange between nonstandard data processing and communications equipment, ASCII is recognized by the American National Standards Institute (ANSI). Also refers to text that has been converted to ASCII code. Unlike text containing special formatting, ASCII can be imported and exported by most application programs without conversion and requires no special software for display and printingASCII text is also known as vanilla textClick here to learn more about ASCII, courtesy of Wikipedia.

attributed author

A person believed to have written or created a work published anonymously or that is of doubtful authorship (exampleThe Second Maiden's Tragedy attributed to the 17th-century writer Thomas Middleton). Attribution is usually based on supporting evidence, but uncertainty may arise when the evidence is meager or conflicting (The Two Noble Kinsmen ascribed to John Fletcher but sometimes erroneously attributed to William Shakespeare). In the library cataloging, attributed authorship is indicated in the note area of the bibliographic description. Synonymous with supposed author. Compare with suppositious author.

auction catalog

A list, usually arranged by lot, of the items offered for sale to the highest bidder at an auction. Often illustrated in black and white and/or color, auction catalogs are of value to collectors because they record existence, dates, provenance, number existing, size, condition at time of the sale, prices realized, etc. Click here to see a selection of historic book auction catalogs, courtesy of the American Antiquarian Society, and here to see an example of an online auction catalog.

A work may have two or more joint authors. In library cataloging, the term is used in its broadest sense to include editorcompilercomposercreator, etc. See alsoattributed authorauthorshipcorporate authorlocal authorpersonal author, and suppositious author.

Under U.S. copyright law (Title 17 § 201), the original owner (or owners) of copyright in a work. In the case of works for hire, the employer or other person for whom the work was prepared is considered the author and copyright owner, unless other arrangements are made by the parties in a signed written agreement.

The procedures by which consistency of form is maintained in the headings (names, uniform titles, series titles, and subjects) used in a library catalog or file of bibliographic records through the application of an authoritative list (called an authority file) to new items as they are added to the collection. Authority control is available from commercial service providers.

authority file

A list of the authoritative forms of the headings used in a library catalog or file of bibliographic records, maintained to ensure that headings are applied consistently as new items are added to the collection.

authorized biography

biography written with the explicit consent and sometimes the cooperation of its subject or the subject's family if the biographee is deceased. Authorized biographies are more likely to be scrutinized by reviewers for bias because the biographer may have been expected to overlook or downplay embarrassing events or unflattering traits in exchange for access to firsthand information and confidential sources. Compare with unauthorized biography.

authorized edition

Back issues are usually retained in a back file, which may be stored in a different location in the periodicals section of a library, sometimes converted to a more compact format, such as microfilm or microfiche. In the catalog record, the extent of the back file is indicated in the holdings statement. Synonymous with back numberSee alsoback set dealer.

backlist

All the publications on a publisher's active list that are no longer new, having been published prior to the current season.

The barcode is a Universal Product Code (UPC) issued by the Uniform Code Council (UCC). In libraries barcodes are used to identify books and other materials for circulation and inventory and to link the borrower's library card to the appropriate patron record in automated circulation systems. Click here to learn more about barcodes, courtesy of HowStuffWorks. Also spelled bar codeSee alsoEAN-13 barcode and QR code.

A person who describes and lists books and other publications, with particular attention to such characteristics as authorshippublication dateeditiontypography, etc. The result of this endeavor is a bibliography. A person who limits such efforts to a specific field or discipline is a subject bibliographerSee alsoBibliographical Society of America

bibliographic control

A broad term encompassing all the activities involved in creating, organizing, managing, and maintaining the file of bibliographic records representing the items held in a library or archival collection, or the sources listed in an index or database, to facilitate access to the information contained in them. Bibliographic control includes the standardization of bibliographic description and subject access by means of uniform catalog codeclassification systems, name authorities, and preferred headings; the creation and maintenance of catalogs, union lists, and finding aids; and the provision of physical access to the items in the collection. See alsoauthority control.

bibliographic coupling

The idea that two scholarly papers containing a citation in common are bibliographically related in a way that is likely to be of interest to researchers. A similar relationship, called co-citation coupling, is established between two or more documents when they are both cited in a third. Citation indexing is based on the principle of bibliographic coupling. Synonymous with citation coupling.

bibliographic database

A computer file consisting of electronic entries called records, each containing a uniform description of a specific document or bibliographic item, usually retrievable by authortitlesubject heading (descriptor), or keyword(s). Some bibliographic databases are general in scope and coverage; others provide access to the literature of a specific discipline or group of disciplines. An increasing number provide the full-text of at least a portion of the sources indexed. Most bibliographic databases are proprietary, available by licensing agreement from vendors, or directly from the abstracting and indexing services that create them.

bibliographic description

In a general sense, all the elements of data necessary to conclusively identify a specific document, presented in some form of record.

In library cataloging, the detailed description of a copy of a specific edition of a work intended to identify and distinguish it from other works by the same author, of the same title, or on the same subject. In AACR2, the bibliographic record representing an item in the catalog includes the following standard areas of description: title and statement of responsibility (author, editorcomposer, etc.), editionmaterial specific details, details of publication and distributionphysical descriptionseriesnotes, and standard number and terms of availability (ISBNISSNprice). See alsochief source of information and level of description.

bibliographic format

The standardized sequence and manner of presentation of the data elements constituting the full description of an item in a specific cataloging or indexing system. The machine-readable MARC record format has become the standard for library catalogs in many countries of the world.

bibliographic item

In AACR2, a document or set of documents in any physical format (print or nonprint) that is given a single bibliographic description in cataloging, by virtue of having been publishedissued, released, or otherwise treated as a single entity.

As defined in FRBR (Functional Requirements for Bibliographic Records), a single concrete exemplar of a manifestation of an expression of an intellectual or artistic work, in most cases a single physical object, such as a copy of an edition of a single-volume monograph. All the items constituting a manifestation normally contain the same intellectual/artistic content and are identical in physical form, but variations can occur subsequent to production, as in the case of a monograph rebound by a library. In some cases, an item consists of more than one physical object, for example, a videorecording released on more than one cassette or a multivolume set of reference books. See alsobibliographic record.

bibliographic record

An entry representing a specific item in a library catalog or bibliographic database, containing all the data elements necessary for a full description, presented in a specific bibliographic format. In modern cataloging, the standard format is machine-readable (example: the MARC record), but prior to the use of computers, the traditional format was the catalog card. Compare with catalog recordcheck-in recorditem record, and order recordSee alsobrief recordencoding levelfull record, and record structure.

bibliographic reference

A written or printed citation containing all the information necessary to uniquely identify a bibliographic resource in any format (printaudiovisual, digital, etc.), published or unpublished. Bibliographic references also help to ensure the intellectual integrity of research by crediting persons and organizations whose previous works have contributed to the research. The ANSI/NISO Z39.29 standard for Bibliographic References provides detailed rules and guidelines for the creation of such references (with examples) for a broad audience, including creators of bibliographic references, processors who publish and display references, and the ultimate users of the references.

bibliography

Strictly speaking, a systematic list or enumeration of written works by a specific author or on a given subject, or that share one or more common characteristics (language, form, period, place of publication, etc.). When a bibliography is about a person, the subject is the bibliographee. A bibliography may be comprehensive or selective. Long bibliographies may be published serially or in book form. The person responsible for compiling a bibliography is the bibliographer. The Reference and User Services Association (RUSA) of the American Library Association has developed Guidelines for the Preparation of a Bibliography. Bibliographies are indexed by subject in Bibliographic Index: A Cumulative Bibliography of Bibliographiespublished by H.W. WilsonAbbreviated bibl. Compare with catalogSee alsoBibliographical Society of Americacartobibliographydiscography, and filmography.

In the context of scholarly publication, a list of references to sourcecited in the text of an article or book, or suggested by the author for further reading, usually appearing at the end of the work. Style manuals describing citation format for the various disciplines (APAMLA, etc.) are available in the reference section of most academic libraries and online via the World Wide Web.

bibliometrics

The use of mathematical and statistical methods to study and identify patterns in the usage of materials and services within a library or to analyze the historical development of a specific body of literature, especially its authorshippublication, and use. Prior to the mid-20th century, the quantitative study of bibliographic data and usage was known as statistical bibliographySee alsocitation analysis and informetrics.

bibliomining

The use of statistical methods in the analysis of library records to detect patterns of behavior in groups of patrons and/or staff which might assist library administration in making informed management decisions and marketing library services effectively. Protection of patron privacy is an important consideration in the use of such dataSee alsobibliometrics.

The Survey gathers data from all the depository libraries, supplementing the more in-depth inspections or self-studies performed every 6-7 years.

big red books

A colloquial expression used by reference librarians in directing library users to the Library of Congress Subject Headings list, a multivolume set of large, thick reference books traditionally bound in red covers, usually shelved near the reference desk or the library catalog (click here to view image).

bilingual edition

book or periodical published in two languages, sometimes because both languages are spoken in the country in which the work is published (for example, English and French in Canada) or because the work was co-published in countries with different national languages. Click here to see an example. In some bilingual editions, especially of poetic and dramatic works, the text in the original language is printed facing the translation.

bimonthly

Issued in alternate months (six times per year). Also refers to a serial issued every other month. Compare with semimonthly.

binding copy

A worn book in such poor condition that it needs to be rebound and is worth the expense of rebinding.

biobibliography

reference work combining biographical information with bibliography, either in the form of brief biographical entries with a list of works written by the biographees, sometimes in separate sections (exampleA Biobibliography of Native American Writers, 1772-1924), or longer biographical essays with a list of works written by and about the biographee at the end of each entry (Women in Law: A Bio-Bibliographical Sourcebook). If the subjects are writers, the bibliography may include critical studies (Asian American Novelists: A Bio-Bibliographical Critical Sourcebook). Also spelled bio-bibliography. Compare with author bibliography.

biographical dictionary

A single-volume reference work or set of reference books containing biographical essays about the lives of actual people, sometimes limited to biographees who are deceased. Biographical dictionaries may be general (exampleWebster's Biographical Dictionary), subject-specific (Biographical Dictionary of the History of Technology), or limited to persons of a specific nationality (American National Biography), race (Contemporary Black Biography), field or profession (International Dictionary of Anthropologists), or period or gender (Biographical Dictionary of Ancient Greek and Roman Women). Some are published serially (Current Biography Yearbook). Compare with collective biography.

biographical note

A brief sketch of the life of the author (composerperformer, etc.) of a workprinted at the end of a book, on the dust jacket, on the container, or elsewhere in or on the bibliographic item. Historical works sometimes contain a section of biographical notes in the back matter covering important persons whose names appear in the text. In library cataloging, the presence of a biographical note is indicated in the note area of the bibliographic description, with the name of the author of the note included if given on the item.

biweekly

Issued every two weeks. Also refers to a serial issued at two-week intervals. Used synonymously with semimonthly. Compare with semiweekly.

blankbook

book consisting of clean or ruleleaves for writing or making entries, with printing limited to page headings and/or divisions (see this example). Examples include diariesalbums, scrapbooks, guestbooks, sketchbooks, account books, minute books, log books, exercise books, etc. Because the information recorded in official blankbooks may be of permanent value, good-quality paper and durable bindings are generally used. A blankbook should open flat for ease of use. Also spelled blank book.

bleaching

The fading of book covers, inks, and pigments used in illustrations, usually caused by overexposure to natural or artificial light (see this example). Bleaching can be minimized in libraries by switching off lights in unused areas, applying protective material to glass-fronted storage cases, and using light sleeves to filter artificial light.

blue book

In the United States, the popular name for a manual published by a state government listing the names of elected and appointed officials and providing information about government structure, agencies, voting districts, elections, etc., usually bound in blue covers. Compare with red book.

In a more general sense, any official or semi-official authoritative guide, usually published serially (see this example).

blueprint

photographic copy of the detailed plans for constructing a building or other structure, formerly printed in white against a blue ground by the cyanotype process. Blueprints are usually produced in sets, one for each floor for each phase of construction (plumbing, electrical, HVAC, etc.). They are collected by architecture libraries and by archives and special collections for construction projects of historical significance. Blueprints are used by libraries in planning and overseeing the renovationexpansion, and new construction of facilities. To see examples, try a keyword search on the term in Google ImagesSee alsoarchitectural drawing.

board book

durable book of small size designed for very young children, consisting of a few unnumbered pages made of pasteboard covered in glossy paper printed with colorful illustrations and little if any text (see these examples). Board books are often alphabet books or counting books.

book

A collection of leaves of paperparchmentvellum, cloth, or other material (written, printed, or blank) fastened together along one edge, with or without a protective case or cover. The origin of the word is uncertain. It may be derived from the Anglo-Saxon boc (plural bec) or from the Norse bok, meaning "book" or "beech tree," possibly in reference to the wooden boards originally used in binding. Also refers to a literary work or one of its volumes. Compare with monograph.

To qualify for the special parcel post rate classified by the U.S. Postal Service as "media mail," a publication must consist of 24 or more pages, at least 22 of which bear printing consisting primarily of reading material or scholarly bibliography, with advertising limited to book announcements. UNESCO defines a book as a nonperiodical literary publication consisting of 49 or more pages, covers excluded. The ANSI standard includes publications of less than 49 pages that have hard covers. Abbreviated bkSee alsoart bookartist's bookboard bookchildren's bookcodexcoffee table bookgift booklicensed bookmanaged bookminiature booknew bookpackaged bookpicture bookpremium bookprofessional bookpromotional bookrare bookreference bookreligious book, and reprint book.

Also, a major division of a longer work (usually of fiction) that is further subdivided into chapters. Usually numbered, such a division may or may not have its own title. Also refers to one of the divisions of the Christian Bible, the first being Genesis.

In reference to a musical play, a volume containing the scenario and dialogue without the score.

bookbin

book catalog

library catalog in the form of a bound or loose-leaf book, whether handwritten, printed, or computer-generated, practical only for small collections.

book drop

A slot, chute, bin, or box to which books and other items borrowed from a library may be returned, especially during hours when the facility is closed. Book drops may be free-standing (usually outside the walls of the library) or built into the circulation desk or an exterior wall. Security is an important consideration in the design of an after-hours book drop. Libraries have suffered damage from hazardous materials deposited by malicious persons in book drops. Click here to see a free-standing model and here to see a drive-up book drop. See alsosmart book drop.

bookmark

A narrow strip of paper, leather, ribbon, or other thin, flexible material placed between the pages of a book to mark a place. Hand-crafted decorative bookmarks are sometimes given as gifts. In older and more expensive editions, a piece of narrow ribbon longer than the length of the pages, called a register, is sometimes glued to the top of the spine to serve as a bookmark.

When and where the use of bookmarkers originated had not been established, but a variety of devices are known to have been in use from the 12th century on. Some medieval manuscripts have small finger tabs or knotted strips of parchment (sometimes marked with pigment) attached to the fore-edge (see these examples in a 16th-century printed missal, courtesy of the Koninklijke Bibliotheek). In other volumes linen or silk ribbons, or long strips of parchment, were attached to the headband, sometimes with an ornament or reading device suspended from the free end. Click here to see an online exhibition of paper bookmarks intended as keepsakes, courtesy of the Friends of the Amherst College Library. To explore the variety of bookmarks, try a keyword search on the term "bookmarks" in Google Images.

In computing, to mark a document or a specific location in a document for subsequent retrieval. Most Web browser software includes a "bookmark" or "favorites" option that allows an Internet address (URL) to be archived, enabling the user to revisit the site without having to retype the address or repeat the original search from scratch. See alsosocial tagging.

book number

The portion of the call number following the class notation, added to distinguish a specific item within its class. A book number is composed of an author mark appended by the cataloger to subarrange works of the same class by name of author, followed by a work mark added to subarrange works of the same author by title or edition (exampleH5371m in the Dewey Decimal call number 993.101 H5371m assigned to the book titled The Maoris by Charles Higham). Synonymous with book mark.

book pocket

A three-inch-wide strip of stiff paper with a small pocket folded and glued across the bottom third of its height to hold a book card, used in libraries with manual circulation systems (see this example). Available ungummed or with a self-adhesive back, plain or with a date due slip printed at the top, the pocket is affixed to the inside cover or endpaper in books, or to some other part in nonbook items. To enable circulation staff to match card to item at check-in, the front of the pocket and the top of the corresponding card are marked with the call number, name of author, and title of item.

Books in Print (BIP)

A multivolume reference set that lists bookcurrently published or distributed in the United States, by authortitle, and subject (ISSN: 0068-0214). Entries include information useful to acquisitions librarians such as publisherpriceeditionbinding type, and ISBN. Published annually by BowkerBIP includes a directory of publishers in a separate volume. It is supplemented by Forthcoming Books.

Boolean

A system of logic developed by the English mathematician George Boole (1815-64) that allows the user to combine words or phrases representing significant concepts when searching an online catalog or bibliographic database by keywords. Three logical commands (sometimes called "operators") are available in most search softwareThe OR command is used to expand retrieval by including synonyms and related terms in the querySee alsological sumSearch statement: violence or conflict or aggression; The AND command is used to narrow search results. Each time another concept is added using "and," the search becomes more specific. In some online catalogs and databases, the "and" command is implicit (no need to type it between terms). In other interfaces, keywords will be searched as a phrase if not separated by "and." See alsological product.; Search statementviolence and television and children; The NOT command is used to exclude unwanted records from search results. See alsological difference.; Search statementtelevision not news; When two different Boolean commands are used in the same search statementparentheses must be included to indicate the sequence in which they are to be executed (syntax). This technique is called nesting.; Search statementtelevision and (violence or aggression) and children; For a detailed discussion of Boolean logic, please see the entry by Gwyneth Tseng in the International Encyclopedia of Information and Library Science (Routledge, 2003). Click here to see Boolean logic illustrated with Venn diagrams (Ithaca College Library), and here to learn how it works in computer searching, courtesy of HowStuffWorksSee alsoproximity and truncation.

borrower

A person who checks out books and other materials from a library. Most libraries require users to register to receive the borrowing privileges associated with a library card. Some form of identification is usually required of new applicants. Not all library patrons are registered borrowers--in most public libraries and publicly supported academic libraries in the United States, unregistered persons may use reference materials and items in the circulating collection without removing them from library premises. The library privileges to which a borrower is entitled are indicated by the individual's borrower statusSee alsodelinquent borrower.

borrower account

patron's ongoing transactions with a library, including items currently checked outoverdues, unpaid finesholds, etc. Library staff can check the status of an individual's account by examining the patron record. Most automated circulation systems are designed to protect the borrower's confidentiality by deleting transaction history as soon as items are returned and fines paid. See alsoblocked.

borrower status

The borrowing privileges to which a registered borrower is entitled, determined by borrower type as indicated in the patron record. Each library establishes its own list of borrower categories to reflect local conditions. In public libraries, all registered users generally enjoy the same privileges, but in academic libraries, certain privileges, such as length of loan period, may not be the same for faculty and students. In special libraries, privileges may depend on a person's rank in the parent organization.

borrowing privileges

The rights to which a library borrower is entitled, usually established by registering to receive a library card. Such privileges normally include the right to check out books and other materials from the circulating collection for a designated period of time, interlibrary loan, use of special collections, etc. They may be suspended if fines remain unpaid. In most public libraries, all registered users enjoy the same privileges, but in academic libraries, certain privileges, such as length of loan period, may depend on borrower status. In special libraries, borrowing privileges may be determined by a person's rank in the parent organization.

bright copy

copy of an older book that is as fresh and new as the day it was published, a condition likely to command a higher price in the market for antiquarian and used books than a copy of the same edition showing signs of wear. See alsomint.

broad classification

classification system in which the main classes are not extensively subdivided, for use in small libraries that do not require close classification to organize their collections effectively.

In Dewey Decimal Classification, the classification of works in general categories by logical abridgment, even when more specific class numbers are available, for example, use of the class 641.5 Cooking instead of the subclass 641.5945 Italian cooking for a cookbook consisting of recipes for Italian food.

bulletin

periodical, usually in the form of a pamphletissued by a government agencysociety, or other institution, containing announcements, news, and information of current interest, usually more substantial than a newsletter (exampleBulletin of the Atomic Scientists). In a more general sense, any brief report on the latest developments in an ongoing process or situation, issued in print or nonprint formatAbbreviated bullSee alsobulletin board.

bulletin board

A flat notice board, usually attached to a wall near the entrance to a library, used to display announcements of forthcoming events, dust jackets removed from new books recently added to the collectionreading lists, comments and suggestions from library users (sometimes with responses from the library administration), and other information pertinent to library operations. Some libraries use a kiosk for this purpose. Library bulletin boards may be kept locked (example) or unlocked (example). See alsobulletin board system.

CContent

 

call number

A unique code printed on a label affixed to the outside of an item in a library collection, usually to the lower spine of a book or videocassette (see these examples), also printed or handwritten on a label inside the item. Assigned by the cataloger, the call number is also displayed in the bibliographic record that represents the item in the library catalog, to identify the specific copy of the work and give its relative location on the shelf.

In most collections, a call number is composed of a classification number followed by additional notation to make the call number unique. This gives a classified arrangement to the library shelves that facilitates browsing. Generally, the class number is followed by an author mark to distinguish the work from others of the same class, followed by a work mark to distinguish the title from other works of the same class by the same author, and sometimes other information such as publication datevolume numbercopy number, and location symbol.

In Library of Congress Classification (LCC), used by most academic and research libraries in the United States, class notation begins with letters of the English alphabet (example: PN 2035.H336 1991). In Dewey Decimal Classification (DDC), used by most public and school libraries in the United States, class notation consists of arabic numerals (example: 480.0924 W3). U.S. federal government documents are assigned SuDocs numbers (exampleL 2.2:M 76).

camcorder

A self-contained electronic device, introduced by Sony in 1983, that combines the capabilities of a video camera and videocassette recorder (VCR) in the same portable unit. Newer camcorders record video images and sound in digital format and are considerably smaller in size (and lower in price) than earlier analog models. Click here to learn more about the history of the camcorder, courtesy of Wikipedia.

cameo binding

A style of bookbinding popular in Italy from about 1500-1560 in which the centers of the boards forming the cover are stamped in relief in imitation of a coin or medallion. The decoration may be left blind or embellished with ink, silver, or gold leafClick here to see an example done in blind (Southern Methodist University). Synonymous with plaquette binding. Compare with centerpiece.

camera-ready copy (CRC)

In printingcopy typed using word processing software, or produced by some other means, that has been fully edited and is ready to be photographed for platemaking without having to be typeset. Synonymous with camera copy.

campaign biography

The life story of a political candidate, issued at the time of his or her campaign for election to public office. The genre began in the United States in 1817 with the publication of The Life of Andrew Jackson by John Reid and John Henry Easton.

cancellation period

The period of time a library allows a publisherjobber, or other vendor for shipment of a book or item before the order is automatically canceled, usually 90 to 180 days. The item may subsequently be reordered from the same vendor or a different source.

capital expenditure

In budgeting, an allocation made on a one-time basis, usually for the construction of new facilities, the renovation or expansion existing facilities, or a major upgrade of automation equipment or systems, as opposed to the operating budget allocated annually or biennially to meet the ongoing expenses incurred in running a library or library system.

carbon print

The result of a photographic process patented by Joseph Wilson Swann in 1864 and popular until about 1910, in which a thin sheet of paper coated with a layer of light-sensitive gelatin containing a permanent pigment is exposed to ultraviolet light under a negative. The resulting image is transferred under pressure to a second sheet of gelatin-coated paper, then washed in water to set the gelatin, producing a permanent print with a raised surface where the image is darkest. The most commonly used pigments are carbon black and sepia, but a wide range of tints can be used. Because carbon prints contain no silver, they are highly resistant to fading, making them especially suitable for book illustration and commercial editions of photographic prints. Click here to see examples (Getty Museum) and here to learn more about the process, courtesy of Victoria & Albert Museum, London.

card catalog

A list of the holdings of a libraryprinted, typed, or handwritten on catalog cards, each representing a single bibliographic item in the collection. Catalog cards are normally filed in a single alphabetical sequence (dictionary catalog), or in separate sections by authortitle, and subject (divided catalog), in the long narrow drawers of a specially designed filing cabinet, usually constructed of wood (see this example). Most large- and medium-sized libraries in the United States have converted their card catalogs to machine-readable format. Also spelled card catalogue. Compare with online catalog.

case binding

A form of mechanized bookbinding in which a hard cover, called a case, consisting of two boards and an inlay covered in clothleather, or paper, is assembled separately from the book block and attached to it after forwarding by gluing the hinges, sewing supports, and paste-downs to the boards in a process called casing-in or hanging-in. The spine of the case is not adhered to the binding edge of the sections in case binding. When the method was first introduced in 1823, plain cloth was used to cover the boards, but by the 1830s a variety of finishes had been developed and embossing was often added. Click here to see all the parts of a typical case-bound book labeled. See alsorecased.

casebook

book containing records or descriptions of actual cases that have occurred in a professional discipline (law, medicine, psychology, sociology, social work, counseling, etc.), selected to illustrate important principles and concepts, for the use of students as a textbook and practitioners for reference. Legal casebooks are typically plainly bound (see this example). Compare with case study

catalog

comprehensive list of the books, periodicals, maps, and other materials in a given collection, arranged in systematic order to facilitate retrieval (usually alphabetically by authortitle, and/or subject). In most modern libraries, the card catalog has been converted to machine-readable bibliographic records and is available online. The purpose of a library catalog, as stated by Charles C. Cutter in Rules for a Dictionary Catalog (1904), later modified by Bohdan S. Wynar in Introduction to Cataloging and Classification (8th ed., 1992), is to offer the user a variety of approaches or access points to the information contained in the collection:

Objects:

1. To enable a person to find any work, whether issued in print or in nonprint format, when one of the following is known:
a. The author
b. The title
c. The subject
2. To show what the library has
d. By a given author
e. On a given and related subjects
f. In a given kind of literature
3. To assist in the choice of a work
g. As to the bibliographic edition
h. As to its character (literary or topical)

The preparation of entries for a library catalog (called cataloging) is performed by a librarian known as a cataloger. British spelling is catalogueAbbreviated cat. Compare with bibliography and indexSee alsoclassified catalogdictionary catalogdivided catalog, and online catalog.

In manual cataloging systems, a paper card used to make a handwritten, typed, or printed entry in a card catalog, usually of standard size (7.5 centimeters high and 12.5 centimeters wide), plain or ruled. Click here to see examples, courtesy of the Gustavus Adolphus College Library. With the conversion of paper records to machine-readable format and the use of online catalogs, catalog cards have fallen into disuse. British spelling is catalogue cardSee alsoextension card.

catalog code

A detailed set of rules for preparing bibliographic records to represent items added to a library collection, established to maintain consistency within the catalog and between the catalogs of libraries using the same code. In the United States, Great Britain, and Canada, libraries use the Anglo-American Cataloguing Rules developed jointly by the American Library AssociationLibrary Association (UK), and Canadian Library Association. Synonymous with cataloging code.

cataloger

librarian primarily responsible for preparing bibliographic records to represent the itemacquired by a library, including bibliographic descriptionsubject analysis, and classification. Also refers to the librarian responsible for supervising a cataloging department. British spelling is cataloguer. Synonymous with catalog librarianSee alsoAssociation for Library Collections and Technical Services and Cataloger's Desktop.

cataloging

The process of creating entries for a catalog. In libraries, this usually includes bibliographic descriptionsubject analysis, assignment of classification notation, and activities involved in physically preparing the item for the shelf, tasks usually performed under the supervision of a librarian trained as a cataloger. British spelling is cataloguingSee alsocataloging agencyCataloging and Classification Sectioncataloging-in-publicationcentralized catalogingcooperative catalogingcopy catalogingdescriptive catalogingencoding level, and recataloging.

catalog record

In the manual card catalog, all the information given on a library catalog card, including a description of the item, the main entry, any added entries and subject headings, notes, and the call number. In the online catalog, the screen display that represents most fully a specific edition of a work, including elements of description and access points taken from the complete machine-readable bibliographic record, as well as information about the holdings of the local library or library system (copieslocation, call number, status, etc.) taken from the item records attached to the bibliographic record. British spelling is catalogue record. Compare with entry.

catchword

A word or part of a word printed in boldface or uppercase at the top of a column or page in a dictionary or encyclopedia that repeats the first and/or last heading appearing in the column or on the page. Synonymous with guideword. Compare in this sense with catch letters.

In medieval manuscripts and early printed books, a word or part of a word appearing in the lower margin of the last page of a quire that duplicates the first word on the first page of the following quire, enabling the binder to assemble the gatherings in correct sequence. In hand-copied books, the sequence of catchwords is unique to a specific copy. Michelle Brown notes in Understanding Medieval Manuscripts (Getty Museum/British Library, 1994) that the practice was probably introduced into Europe by the Moors. Click here to see an examples in a 14th-century English psalter (British Library, Harley 2888), Columbia University), and here to see a decorated example in a late 14th-century Book of Hours (Syracuse University Library). Click here to see catchwords in a printed book, courtesy of the University of Pittsburgh Libraries.

Also refers to a word or phrase repeated so frequently that it has become a motto or slogan. Compare in this sense with cliché.

catchword title

partial title composed of an easily remembered word or phrase likely to be used as a heading or keyword in a search of the library catalog, sometimes the same as a subtitle or the alternative title. Synonymous with catch title.

ceased publication

Said of a periodical or newspaper no longer published (see this example, courtesy of the Koninklijke Bibliotheek). Publication may eventually resume under the same title or an altered title. Also said of a work published in more than one volume, which was never completed. Library holdings are indicated in a closed entry. Compare with canceled and discontinuedSee alsocessation.

census

An official count and statistical analysis of the living population of a species (human or nonhuman) in a given geographic area (city, county, state, province, country, etc.) taken at a particular point in time. A census is distinct from a sampling in which information obtained about a portion of a population is used as the basis for generalization about the whole. The earliest known census of taxpaying households was recorded in China in the 3rd century B.C. More complete enumerations were conducted for military and tax purposes in ancient Rome by special magistrates called censors. The development of the modern census began in Europe in the 17th century and today includes questions concerning age, gender, ethnicity, income, housing, etc., formulated to generate data used in social planning, political redistricting, business marketing, etc. In most countries, participation in the census is compulsory, but the information collected on individual households and businesses is confidential.

In the United States, the national census, mandated by the federal Constitution, is conducted every ten years by the U.S. Census Bureau, which reports the detailed results in statistical form by state. Census data is used to apportion seats in Congress and to gather demographic and economic information about citizens and other residents, later compiled and analyzed in federal statistical publications. U.S. census data is available in the government documents collections of larger libraries and online at: www.census.govSummary tables are published in the Statistical Abstract of the United States, prepared annually since 1879 and available in the reference section of most libraries in the United States. See alsocensus tractDomesday Book, and TIGER files.

centralized cataloging

The preparation of bibliographic records for books and other library materials by a central cataloging agency that distributes them in printed and/or machine-readable form to participating libraries, usually for a modest fee. Also refers to the cataloging of materials for an entire library system at one of its facilities, usually the central library, to achieve uniformity and economies of scale. Also spelled centralized cataloguing.

centralized processing

The practice of concentrating in a single location all the functions involved in preparing materials for library use, as opposed to technical processing carried out at multiple locations within a library or library system. Centralization allows processing methods to be standardized, but increased efficiency may be offset by the cost of distributing materials to the units where they will be used.

chapter heading

A display heading in a book or manuscript usually consisting of a roman numeral indicating the chapter number, followed by the chapter title, written or printed on the first page of the chapter in uniform style and position above the first paragraph of the text. Set in a type size larger than the text and running heads, chapter heads are sometimes embellished with an illustration or head-piece in older editions. See alsochapter drop and dropped heads.

chat

Synchronous (real time) computer conferencing capability between two or more users of a network (LANWANInternet) by keyboard rather than voice transmission, in which everyone who is logged on can see the messages others are typing. Chat rooms are often devoted to a particular theme or topic. Most Internet service providers offer such online discussion forums to their subscribers. See alsoinstant messaging.

check digit

character added to a sequence of digits, related arithmetically to the sequence in such a way that input errors can be automatically detected whenever the sequence is entered as data into a computer, for example, the last character of the ISBN. When a calculated check digit is the number 10, it is represented as the character X. Synonymous with checksum.

checked out

The circulation status of an item that has been charged to a borrower account and is not due back in the library until the end of the loan period. In the online catalog, the due date is usually displayed as a status code in the catalog record to indicate that the item is currently unavailable for circulation. Synonymous with on loanSee alsooverduerecall, and renew.

check-in

The ongoing process of recording the receipt of each issue of a newspaper or periodical, a routine task accomplished by the serials department of a library, manually or with the aid of an automated serials control system. Some automated systems allow the patron to view the check-in record for a given titleSee alsoclaim.

checklist

comprehensive list of books, periodicals, or other documents that provides the minimum amount of description or annotation necessary to identify each work--briefer than a bibliography. Also, the log kept by a library to record the receipt of each number of a serial publication or part of a work in progress. Also refers to a list of items required, or procedures to be followed, such as the steps in a library's opening or closing routine. Also spelled check-list.

checkout slip

Instead of stamping the date due slip in each item at checkout, many libraries now print a computer-generated slip listing the items a patron has checked out. A good checkout slip should facilitate return of materials by reminding the patron of the date on which the borrowed items are due back at the library. Checkout slips should also give the library's name and phone number, respect the user's privacy, include item type for clarity, and be easy to read. Some libraries also use checkout slips to facilitate renewal, promote library events, broadcast library policy changes, and alert users to special hours. For design suggestions, see the brief article Consider the Checkout Slip by Aaron Schmidt in the February 1, 2012 issue of Library Journal. Also spelled check-out slip.

circulating book

book that can be charged to a borrower account for use inside or outside the library facility, as opposed to one restricted to library use only. Compare with noncirculating.

circulating collection

Books and other materials that may be checked out by registered borrowers for use inside or outside the library. In most academic and public libraries in the United States, circulating materials are shelved in open stacks to facilitate browsing. Compare with noncirculating.

circulation

The process of checking books and other materials in and out of a library. Also refers to the total number of itemchecked out by library borrowers over a designated period of time and to the number of times a given item is checked out during a fixed period of time, usually one year. In public libraries, low circulation is an important criterion for weeding items from the collection. Books for which circulation is anticipated to be high may be ordered in multiple copies to satisfy demand or given a more durable binding to withstand heavy use. Some online circulation systems provide circulation statistics by classification and material type for use in collection development. Circulation is a fundamental to access servicesAbbreviated circ.

In publishing, the number of copies distributed of each issue of a serial publication, including complimentary copies, single-copy retail sales, and copies sent to paid subscribers. Compare with total circulation.

circulation desk

The service point at which books and other materials are checked in and out of a library, usually a long counter located near the entrance or exit, which may include a built-in book drop for returning borrowed materials. In small and medium-sized libraries, items on hold or reserve are usually available at the circulation desk, which is normally staffed by one or more persons trained to operate the circulation system and handle patron accounts. To see modern examples, try a keywords search on the term in Google Images. Synonymous with loan desk. Compare with reference desk.

circulation status

The conditions under which a specific item in a library collection is available for use. An item may be on orderin process, at the bindery, for library use onlyavailable to be checked out, on loan until a certain due daterecently returnedmissinglost, or billed. Compare with loan status.

citation

In the literary sense, any written or spoken reference to an authority or precedent or to the verbatim words of another speaker or writer. In library usage, a written reference to a specific work or portion of a work (bookarticledissertationreport, musical composition, etc.) produced by a particular authoreditorcomposer, etc., clearly identifying the document in which the work is to be found. The frequency with which a work is cited is sometimes considered a measure of its importance in the literature of the field. Citation format varies from one field of study to another but includes at a minimum author, title, and publication date. An incomplete citation can make a source difficult, if not impossible, to locate. Abbreviated citeSee alsocitation analysiscitation indexpreferred citation, and self-citation.

citation analysis

bibliometric technique in which workcited in publications are examined to determine patterns of scholarly communication, for example, the comparative importance of books versus journals, or of current versus retrospective sources, in one or more academic disciplines. The citations in student research papers, theses, and dissertations are also examined by librarians for purposes of collection evaluation and development. Synonymous with citation checking.

citation index

A three-part index in which workcited during a given year are listed alphabetically by name of author cited, followed by the names of the citing authors (sources) in a "Citation Index." Full bibliographic information for the citing author is given in a "Source Index." Also provided is a "Subject Index," usually listing articles by significant words in the titleResearchers can use this tool to trace interconnections among authors citing papers on the same topic and to determine the frequency with which a specific work is cited by others, an indication of its significance in the literature of the field.

Citation indexing originated in 1961 when Eugene Garfield, Columbia University graduate in chemistry and library science and founder of the fledgling Institute for Scientific Information (ISI), received an NIH grant to produce the experimental Genetics Citation Index, which evolved into the reference serial Science Citation Index. ISI subsequently published Social Sciences Citation Index beginning in 1972 and Arts & Humanities Citation Index from 1978. See alsobibliographic coupling and citation chasing.

claim

A notice from a library informing the publisher or subscription agent that a specific issue of a newspaper or periodical on subscription, or item on continuation order, has not been received within a reasonable time, with a request that a replacement copy be sent. Claimed items are noted in the check-in record attached to the bibliographic record that represents the publication in the library catalogSee alsoclaim report.

Also refers to the process used by a depository library in the Federal Depository Library Program (FDLP) to inform the U.S. Government Printing Office (GPO) that an item number on its list of selections was included on a shipping list, but the document was not received. Claims must be filed by the depository within 60 days of receipt of the shipping list, except when a raincheck was issued. Claims can be filed online using the Web Claim form available on the FDLP Desktop.

claim report

The publisher's or vendor's response regarding the status of a claim made by a library for material not received as expected on subscription or continuation order. Synonymous with claim check.

classification

The process of dividing objects or concepts into logically hierarchical classes, subclasses, and sub-subclasses based on the characteristics they have in common and those that distinguish them. Also used as a shortened form of the term classification system or classification scheme. See alsoCataloging and Classification Section and cross-classification.

classification schedule

The names assigned to the classes and subdivisions of a classification system, listed in the order of their symbolic notation. In a hierarchical classification system, the arrangement of the schedule(s) indicates logical subordination. For example, in Dewey Decimal Classification the schedules consist of the class numbers 000-999, the associated headings, and notes concerning use, with logical hierarchy indicated by indention and length of notation. See alsoauxiliary schedulemain schedulerelative index, and schedule reduction.

classification system

A list of classes arranged according to a set of pre-established principles for the purpose of organizing items in a collection, or entries in an indexbibliography, or catalog, into groups based on their similarities and differences, to facilitate access and retrieval. In the United States, most library collections are classified by subject. Classification systems can be enumerative or hierarchicalbroad or close. In the United States, most public libraries use Dewey Decimal Classification, but academic and research libraries prefer Library of Congress ClassificationSee alsoClassification Society of North AmericaColon Classification, and notation.

classified catalog

subject catalog in which entries are filed in the notational order of a pre-established classification system, with bibliographic records under as many subject headings as apply to the content of each item. An alphabetical subject index facilitates the use of a classified catalog, which is usually maintained alongside an author and/or title catalog. Synonymous with classed catalog and class catalog. Compare with dictionary catalog and divided catalog.

classify

To arrange a collection of items (books, pamphlets, maps, videocassettes, sound recordings, etc.) according to a system of classification, based on the characteristics (facets) of each item. Also, to assign a class number to an individual item in a collection, based on its characteristics.

class number

The specific notation used in Dewey Decimal Classification to designate a class, for example, 943.085 assigned to works on the history of the Weimar Republic in Germany. In Library of Congress Classification, the corresponding notation is DD237See alsobase numberdiscontinued numberinterdisciplinary number, and number building.

co-edition

An edition for which two or more publishers share responsibility, for example, The Great Libraries: From Antiquity to the Renaissancepublished in 2000 by Oak Knoll Press and the British Library. In most cases, the original publisher grants the exclusive right to market and distribute the publication within a specific sales territory to one or more other publishers (see co-publishing). The title page of a co-edition may bear the imprint of the originator, of one of the companies granted distribution rights, or of all the co-publishers. Compare with export edition and joint publicationSee alsojoint imprint.

collected edition

An edition of the previously published works of an authorissued in a single volume or uniform set of volumes, usually under a collective title. Compare with author's edition.

collection

In library cataloging, three or more independent works or long excerpts from works by the same author, or two or more independent works or excerpts from works by different authors, not written for the same occasion or for the publication in hand, published together in a single volume or uniform set of volumes, for example, a book of essays written by one or more essayists. Selected by an editor, the works are listed in the table of contents in order of appearance in the textClick here and here to see collected editions of Sir Arthur Conan Doyle's Sherlock Holmes short stories originally published in The Strand Magazine (Lilly Library, Indiana University). Synonymous with collected work. Compare with anthology and compilationSee alsoanalytical entry.

Also refers to a number of documents (books, reports, records, etc.) assembled in a single physical or virtual location by one or more persons, or by a corporate entity, and arranged in some kind of systematic order to facilitate retrievalSee alsolibrary collection.

collection development

The process of planning and building a useful and balanced collection of library materials over a period of years, based on an ongoing assessment of the information needs of the library's clientele, analysis of usage statistics, and demographic projections, normally constrained by budgetary limitations. Collection development includes the formulation of selection criteria, planning for resource sharing, and replacement of lost and damaged items, as well as routine selection and deselection decisions.

Large libraries and library systems may use an approval plan or blanket order plan to develop their collections. In small- and medium-sized libraries, collection development responsibilities are normally shared by all the librarians, based on their interests and subject specializations, usually under the overall guidance of a written collection development policy. Compare with collection managementSee alsoCollection Development and Evaluation SectionCollection Management and Development Section, and collaborative collection development.

collection development policy (CDP)

A formal written statement of the principles guiding a library's selection of materials, including the criteria used in making selection and deselection decisions (fields covered, degrees of specialization, levels of difficulty, languages, formats, balance, etc.) and policies concerning gifts and exchanges. An unambiguously worded collection development policy can be very helpful in responding to challenges from pressure groups.

collective title

In library cataloging, the title proper of a bibliographic item containing several works by one or more authorissued in a single volume or uniform set of volumes, each with its own title distinct from that of the whole. Also refers to the title assigned by a cataloger to a group of separately published materials cataloged collectively.

collective work

For purposes of copyright (17 USC 101), a work in which a number of contributions by one or more authors, each a separate and independent work, are assembled, usually by an editor, to constitute a whole. Included are individual issues of a periodicalanthologiescollections of essays, conference proceedings, etc.

Colon Classification

classification system in which subjects are analyzed into facets based on their uses and relations, then represented by synthetically constructed classes with the parts separated by the colon (:). Developed by S.R. Ranganathan in the 1930s, Colon Classification is used in libraries in India and in research libraries throughout the world. To learn more about colon classification, see Wikipedia.

compact edition

An edition in which the physical size of a long work is reduced, usually by altering the format without changing the content, for example, The Compact Oxford English Dictionary (second edition), reproduced micrographically and issued in a slipcase with a microprint reader. Compare with concise edition.

compact storage

library shelving area, often reserved for low-use materials, in which narrow aisles, higher-than-normal shelves, and/or compact shelving is employed to maximize storage capacity (see this example at Virginia Commonwealth University). The building must be structurally capable of supporting the additional weight. Compact shelving with movable parts may be subject to electrical or mechanical failure. See alsoautomated storage and retrieval system.

 Concurrent access 

the fact of allowing more than one user to use a computer system at the same time: The licence type you choose will depend on the number of people requiring concurrent access.

contemporary binding

binding made in the same time period as the text block, but not necessarily at the same time the text was printed or hand-copied. Older books are often rebound in the style of a later period and the original binding discarded when badly worn.

content analysis

Close analysis of a work or body of communicated information to determine its meaning and account for the effect it has on its audienceResearchers classify, quantify, analyze, and evaluate the important words, concepts, symbols, and themes in a text (or set of texts) as a basis for inferences about the explicit and implicit messages it contains, the writer(s), the audience, and the culture and time period of which it is a part. In this context, "text" is defined broadly to include books, book chapters, essays, interviews and discussions, newspaper headlines, periodical articles, historical documents, speeches, conversations, advertising, theater, informal conversation, etc. Click here to learn more about content analysis, courtesy of the Writing Center at Colorado State University.

conversion fee

The fee charged libraries in the United States by some vendors based in foreign countries to convert payments made in U.S. dollars into the currency of the vendor's country. The fee should be stated separately, rather than included in the cost of the materials purchased. Payments made to foreign vendors that have bank accounts in the United States can be made in dollars without penalty.

cooperative cataloging

An arrangement in which a library or library system agrees to follow established cataloging practices and work in automated systems or utilities that facilitate the creation of bibliographic and authority records in a form that can be shared with other libraries. In North America, cooperative cataloging is facilitated by the uniform cataloging practices established in Anglo-American Cataloguing Rules (AACR2). OCLC is the bibliographic utility used for cooperative cataloging in the United States. Synonymous with shared catalogingSee alsoNational Union Catalog of Manuscript Collections.

cooperative publication

A federal government publication required to be self-sustaining through sale, usually on a cost-recovery basis, not distributed free of charge to depository libraries through the Federal Depository Library Program (FDLP). Click here to see a U.S. Forst Service example.

cooperative reference

Reference services provided by referring the user or the user's question(s) to library or information personnel at another institution, according to a formally established system of protocols, rather than on an informal case-by-case basis. When such services are provided digitally, the service is known as collaborative reference. The Reference and User Services Association (RUSA) of the American Library Association (ALA) has developed Guidelines for Cooperative Reference Service Policy Manuals (June 2006) to assist libraries in establishing and evaluating cooperative reference service.

co-publishing

The simultaneous publication of an edition by two or more publishers, usually in different countries, to achieve economies of scale when the home market is not sufficient to guarantee a reasonable profit. Typically, a work is printed in the country of the originating publisher and then supplied to a publisher in another country with a title page bearing the imprint of the second publisher (or both). Subsequent printings may occur independently or cooperatively. In journal publishing, the result may be separate editions for each country or a bilingual edition marketed in both countries. Compare with export edition.

copybook

manual of penmanship, calligraphy, arithmetic, or geography which includes instructional text and examples, with space left blank to allow the pupil to practice his or her skills by imitation (see this example). The first American copybook was The American Instructor: Or, Young Man's Best Companion by George Fisher, first published in 1748. Also spelled copy book.

copy cataloging

Adaptation of a pre-existing bibliographic record (usually found in OCLCNUC, or some other bibliographic database) to fit the characteristics of the item in hand, with modifications to correct obvious errors and minor adjustments to reflect locally accepted cataloging practice, as distinct from original cataloging (creating a completely new record from scratch). Synonymous with derived cataloging.

copyright

The exclusive legal rights granted by a government to an authoreditorcompilercomposerplaywrightpublisher, or distributor to publish, produce, sell, or distribute copies of a literary, musical, dramatic, artistic, or other work, within certain limitations (fair use and first sale). Copyright law also governs the right to prepare derivative works, reproduce a work or portions of it, and display or perform a work in public.

Such rights may be transferred or sold to others and do not necessarily pass with ownership of the work itself. Copyright protects a work in the specific form in which it is created, not the idea, theme, or concept expressed in the work, which other writers are free to interpret in a different way. A work never copyrighted or no longer protected by copyright is said to be in the public domainSee alsocopyright compliancecopyright depositorycopyright piracydigital rightsinfringementintellectual propertyinternational copyright, and Public Lending Right.

In 1710, the first copyright law in England (Statute of Anne) gave protection to the author for 14 years, renewable for a second period of equal length. In the United States, the first federal copyright law, passed in 1790, also provided protection for 14 years, renewable for an additional 14 years if the author survived the first term. Congress extended the term in 1831 and 1909, then changed the duration of copyright to life of the author plus 50 years, effective January 1, 1978. In 1998, the controversial Copyright Term Extension Act (CTEA) lengthened the period to life of the author plus 70 years for works published on or after January 1, 1978, the same as in Europe. For anonymous works, pseudonymous works, and works for hire the period is 95 years from year of first publication or 120 years from year of creation, whichever expires first. Library and consumer groups including the American Library Association (ALA) filed amicus briefs in support of a challenge (Eldred v. Ashcroft), but on January 15, 2003 the U.S. Supreme Court upheld the CTEA by a 7-2 vote. Copyright is controlled by Congress and administered by the U.S. Copyright Office of the Library of Congress (click here to see the U.S. Copyright registration of L. Frank Baum's The Wonderful Wizard of Oz). International copyright is governed by the Berne Convention and the Universal Copyright Convention.

Notice of copyright usually appears on the verso of the title page of a book in the form of a small "c" inside a circle ©, the abbreviation "Copr.," or the word "Copyright" followed by year of publication, name of the owner of copyright, and the phrase "all rights reserved." Because copyright law is highly complex, accurate interpretation often requires the advice of a legal specialist. Click here to learn more about Copyright & Fair Use in the United States, courtesy of Stanford University Libraries, or see the Copyright Crash Course provided by the University of Texas. See alsoabandonment of copyrightCopyright Clearance CenterDigital Millennium Copyright Act, and International Copyright Information Centre.

copyright compliance

The responsibility of a library to ensure that its interlibrary loan requests, reserve materials, instruction guides, Web pages, etc., conform to existing copyright law. In the OCLC interlibrary loan system, the codes ccg ("conforms to copyright guidelines") and ccl ("conforms to copyright law") are used by the borrowing library to inform the lending library that a request is compliant. See alsoCopyright Clearance Center, Inc.

copyright date

The year in which a work was first published, usually printed in the copyright notice on the verso of the title page, sometimes following the letter "c" with a circle around it (see this example). If more than one copyright date is given, the earliest is the date of the first edition, which is the same as the date of first publication. Subsequent dates indicate revisions in the text of an extent requiring renewal of copyright.

copyright holder

The person(s) or corporate body possessing the exclusive legal rights granted by a government to publish, produce, sell, or distribute copies of a literary, musical, dramatic, artistic, or other work, within certain limitations (fair use), usually the authoreditorcompilercomposerplaywrightpublisher, or distributor. In the United States, such rights are granted by the U.S. Copyright Office when a work is registered for copyright. The name of the copyright holder is given in the copyright notice, usually printed on the verso of the title page of a book. Synonymous with copyright owner.

copyright notice

A formal announcement of legal status appearing conspicuously on all copies of a work protected by copyright and published by authority of the copyright owner. In the United States, it consists of three parts: (1) the symbol "c" inside a small circle © and the abbreviation Copr. or the word Copyright, followed by (2) year of first publication and (3) name of copyright holder. In printed books, the copyright notice appears on the verso of the title page (see this example).

copyright page

The page of a book, in most editions the verso of the title page, bearing official notice of copyright, usually the copyright symbol ("c" inside a small circle) or the word Copyright or its abbreviation (Copr.), followed by year of first publication, name of copyright holder, country of publication, and other notice and rights information (see this example).

copyright piracy

The systematic unauthorized reproduction or use, without permission and recompense, of a work protected by copyright law, usually for the purpose of profiting from such activity. This type of egregious infringement is subject to legal action by the copyright owner(s) in countries that have accepted international copyright agreements, but in countries that have not, the holder of intellectual property rights may have little recourse. See alsopirated edition.

core collection

collection representative of the basic information needs of a library's primary user group. In public libraries, core collections are selected in anticipation of popular demand and maintained on the basis of usage. In academic libraries, selection is based on curriculum need, and collections are maintained to meet the research interests of students and faculty. Also refers to an initial collection developed for a new library, usually with the aid of standard lists and other selection aids (exampleResources for College Libraries published by the American Library Association).

core journal

A scholarly journal that reports original research of such significance to the academic community that the publication is considered indispensable to students, teachers, and researchers in the discipline or subdiscipline. For this reason, it is included in the serialcollections of academic libraries supporting curriculum and research in the field (exampleAmerican Historical Review in American history). Compare with primary journal.

In public libraries, a periodical so essential to meeting the information needs of a wide range of users that it is included in most general serials collections (exampleScientific American).

corporate name

The official name by which a corporate body such as an association, commercial enterprise, government agency, institution, or other organization is identified, used by libraries in cataloging publicationissued in its name (exampleSpecial Libraries Association). Form of entry is subject to authority control. Synonymous with collective nameSee alsogeographic name and personal name.

cost-effective

A decision or practice that reduces expenditure in relation to the amount of resources invested (time, money, materials, etc.). Monetary savings can be difficult to determine when costs are intangible, intermittent, or incurred over an extended period of time.

cost projection

In acquisitions, a forecast made by a vendor, based on information on current economic trends and from publishers and other sources, concerning the future inflation rate for various categories of materials (books, periodicals, etc.). Libraries use such informed estimates in collection management to allocate budgets, particularly for serialcollections.

cost-recovery

A product or service offered at a price that allows the vendor or provider to cover costs incurred without generating a profit, for example, document delivery service in most academic libraries.

counterproof

An impression made by running a newly struck print through a press against second sheet while the ink is still wet, producing an image that is the reverse of the print but in the same direction as the engraved plate, useful to the artist in making corrections. A counterproof can be identified not only by the reversal, but also by its flatter image and weaker impression. Click here to see an example, courtesy of the Metropolitan Museum of Art.

country of origin

The country in which a bookpamphletserial, etc., is published, determined by the geographic location of the editorial office responsible for producing its intellectual content (ALCTS Serials Acquisitions Glossary, Chicago, 1993).

course catalog

comprehensive list, usually published annually, of all the courses taught at a school, college, or university during a given academic year, usually arranged by department and course number, with brief descriptions of course content and a list of instructors with their credentials at the end. Institutions offering both undergraduate and graduate programs may publish separate catalogs. Course catalogs for educational institutions in the United States and around the world are available online in the searchable database CollegeSource Online. Synonymous with college catalog.

craft book

book which has, as its subject, work traditionally done by hand, such as knitting, sewing, flower arranging, stenciling, or model-making. Some publishers specialize in craft books, for example, Taunton Press.

critical abstract

An abstract that includes a brief evaluation of the significance of the work abstracted and/or the style of its presentation, usually written by a subject specialist. An example can be seen in the Appendix to ANSI/NISO Z39.14 Guidelines for Abstracts. Compare with indicative abstract and informative abstract.

critical annotation

In a bibliography or list of references, an annotation that includes a brief evaluation of the source cited, as opposed to one in which the content of the work is described, explained, or summarized.

critical edition

An edition of a work based on scholarly research and close examination of earlier manuscripts, texts, documents, letters, etc., that sometimes includes analysis and commentary by one or more qualified scholars who have studied and interpreted its meaning and significance (see this example). See alsocritical apparatus.

cross-reference

A reference from a heading to one or more other headings in the same catalogindex, or reference work. The most common are see references, instructing the user to look elsewhere for the preferred form of the heading, and see also references, directing the user to related headings under which additional information may be found. A work containing cross-references is said to have syndetic structureAbbreviated x-refSee alsoblind referenceexplanatory reference, and omnibus reference.

Examples:

Librarianship

See Library science

current awareness service

A service or publication designed to alert scholars, researchers, readers, customers, or employees to recently published literature in their field(s) of specialization, usually available in special libraries serving companies, organizations, and institutions in which access to current information is essential. Such services can be tailored to fit the interest profile of a specific individual or group. Some online catalogs and bibliographic databases include a "preferred searches" option that allows the library user to archive search statements and re-execute them as needed. Synonymous with selective dissemination of informationSee alsocurrent contents.

current bibliography

bibliography that includes only references to recently published sources on a subject or in a specific field or discipline (exampleAnnual Bulletin of Historical Literature published by the Historical Association, London). The opposite of retrospective bibliography.

current contents

periodical that reproduces the tables of contents of the leading scholarly journals in an academic discipline or field to assist researchers in keeping abreast of the most recently published literature in their areas of interest or specialization, usually published weekly or monthly. Because currency is the raison d'être of this type of publicationlibraries may limit back files to the most recent three to five years. See alsocurrent awareness service.

current issue

The latest number of a serial publication, bearing the most recent issue date. In some librariescurrent issues are displayed with the front cover facing forward on sloping shelves or on a periodical stand to facilitate browsingBack files are typically stored in a different location, sometimes on microfilm or microfiche to conserve space. Synonymous with current number. Compare with back issueSee alsofirst issue.

custom binding

book bound to the specifications of its owner or a dealer or in accordance with special instructions from the publisher, rather than the general instructions for the edition. Some binderies specialize in custom binding (see this example).

Cutter number

A system of alphanumeric author marks developed by Charles A. Cutter to permit the subarrangement of items of the same classificationalphabetically by author's last name. A Cutter number consists of one to three letters from the name, followed by one or more arabic numerals from the Cutter Table added to the end of the call number by a cataloger. Synonymous with Cutter author markSee alsowork mark.

dcontent

 

data

The plural of the Latin word datum, meaning "what is given," often used as a singular collective noun. Facts, figures, or instructions presented in a form that can be comprehended, interpreted, and communicated by a human being or processed by a computer. Compare with information and knowledgeSee alsodata bankdatabasedata set, and metadata.

data bank

Sometimes used synonymously with database, the term applies more specifically to a collection of nonbibliographic data, usually numeric (exampleChild Trends DataBank). Large data banks containing information about individuals (social security numbers, credit history, health records, etc.) have become the subject of controversy as the rapid development of high-speed information technology poses new threats to personal privacy.

database

A large, regularly updatefile of digitized information (bibliographic records, abstracts, full-text documents, directory entries, images, statistics, etc.) related to a specific subject or field, consisting of records of uniform format organized for ease and speed of search and retrieval and managed with the aid of database management system (DBMS) softwareContent is created by the database producer (for example, the American Psychological Association), which usually publishes a print version (Psychological Abstracts) and leases the content to one or more database vendors (EBSCOOCLC, etc.) that provide electronic access to the data after it has been converted to machine-readable form (PsycINFO), usually on CD-ROM or online via the Internet, using proprietary search software.

Most databases used in libraries are catalogs, periodical indexes, abstracting services, and full-text reference resources leased annually under licensing agreements that limit access to registered borrowers and library staffAbbreviated db. Compare with data bankSee alsoarchival databasebibliographic databaseembedded databasemetadatabase, and niche database.

database management system (DBMS)

A computer application designed to control the storageretrievalsecurity, integrity, and reporting of data in the form of uniform records organized in a large searchable file called a database. The range of available DBMS software extends from simple systems intended for personal computers to highly complex systems designed to run on mainframes.

data conversion

The process of translating data from one form to another, usually from human-readable to machine-readable format (or vice versa), from one file type to another, or from one recording medium to another, for example, from film to videotape or videodisc using a telecine.

data mining

The process of using database applications to identify previously undetected patterns and relationships within an existing set of data, for example, common interests among the clientele of a business or other organization.

data processing (DP)

The systematic performance of a single operation or sequence of operations by one or more central processing units on data converted to machine-readable format to achieve the result for which the computer program that controls the processing was written, for example, the compilation of circulation statistics from records of circulation transactions occurring in a library over a given period of time.

data set

A logically meaningful collection or grouping of similar or related data, usually assembled as a matter of record or for research, for example, the American FactFinder Data Sets provided online by the U.S. Census Bureau or the National Elevation Dataset available from the U.S. Geological Survey. Also spelled datasetSee alsosocial science data set.

data visualization

The use of electronic tools (software applications) to represent data in the form of charts, maps, tag clouds, animations, or any graphical means to make content easier to understand. Graphic representations of data may reveal hidden patterns and highlight connections among elements not obvious from numerical data. For scholars whose conclusions depend on interpretation of complex statistics, data visualization may facilitate communication to a wider audience. (Adapted from EDUCAUSE.)

deep linking

link made from a Web document to the interior of another Web site, bypassing the second site's homepage, usually without any indication that a shortcut has been taken. Deep linking raises digital rights issues, particularly for commercial entities that derive income from advertising on their main page. Likelihood of litigation depends on the type of site involved and the nature of the content accessed. Libraries should seek permission before deep linking from their Web pages.

definitive edition

An edition of the complete text of an author's work or works, usually edited and published after the individual's death in a form considered final and authoritative, often including the critical apparatus documenting variations in the work and explaining the editor's choice of version. Also refers to the text of an anonymous work considered by scholars or other experts, upon close examination, to be closest to the original version. Compare with authorized editionSee alsocritical edition and variant edition.

delayed publication

book or periodical not issued on schedule, usually due to delays in production. Also refers to new information not published in a timely manner, for whatever reason.

delivery time

The amount of time it takes to receive materials ordered from a vendor, usually 1-3 months. Delivery time varies with type of material, amount of information provided by the library, and specific vendor. From book jobbers that maintain adequate inventories, libraries can expect receipt of an initial shipment containing 75-80 percent of materials ordered within 2 weeks of date of order. Vendors used by academic libraries typically deliver within 6-8 weeks. As a general rule, materials recently published by major houses are delivered faster than older publicationissued by smaller companies. Titles published abroad may take longer because international shipping requires more time than domestic shipping. A service charge is usually added for a rush order. Some vendors automatically cancel orders that remain unfilled after 6 months, but others leave them open indefinitely or expect the library to specify the action to be taken. See alsoclaim.

deluxe edition

An edition printed on better quality paper than the standard trade edition, sometimes from specially cast type, usually bound in leather or some other material of fine quality (see this example). Deluxe editions may also be larger in size, more lavishly illustrated, and published in limited edition. Also spelled de luxe edition. Synonymous with fine edition and luxury editionSee alsodeluxe binding.

depth indexing

An indexing system that attempts to extract all the concepts covered in a work, including any subtopics, as opposed to summarization, in which a work is indexed only under its dominant subjectLibrary catalogers have traditionally looked for the single concept that best describes the entire content of an item, leaving depth indexing to commercial services that index parts of items (articles in periodicals, book chapters, essays in collections, etc.).

derivative indexing

A method of indexing in which a human indexer or computer extracts from the title and/or text of a document one or more words or phrases to represent subject(s) of the work, for use as headings under which entries are made. Synonymous with derived indexing and extractive indexing. Compare with assignment indexingSee alsoautomatic indexing and machine-aided indexing.

descriptive bibliography

The close study and description of the physical and bibliographic characteristics of books and other materials, including detailed information about authortitlepublication history, formatpaginationillustrationprintingbinding, appearance, etc., as opposed to an examination of content. Also refers to a work that is the result of such study. Descriptive bibliography is considered a branch of analytical bibliography.

descriptive cataloging

The part of the library cataloging process concerned with identifying and describing the physical and bibliographic characteristics of the item, and with determining the name(s) and title(s) to be used as access points in the catalog, but not with the assignment of subject headings and genre/form terms. In the United States, Great Britain, and Canada, descriptive cataloging is governed by Anglo-American Cataloguing Rules (AACR2). See alsoauthority control and subject analysis.

descriptive metadata

Data about an information resource that is intended to facilitate its discovery, identification, and selection. Descriptive metadata is also used to bring together all the versions of a work in a process called collocation, and for acquisition purposes. When viewed as metadata, traditional library cataloging is descriptive, as are such schemes as the Dublin Core Metadata Element Set and the VRA (Visual Resources Association) Core. Descriptive metadata is also used for evaluation, both narrative (reviews, etc.) and formal (content ratings); for linkage (relationships between a resource and other things); and for usability. Compare with administrative metadata and structural metadata.

dictionary

A single-volume or multivolume reference work containing brief explanatory entries for terms and topics related to a specific subject or field of inquiry, usually arranged alphabetically (exampleDictionary of Neuropsychology). The entries in a dictionary are usually shorter than those contained in an encyclopedia on the same subject, but the word "dictionary" is often used in the titles of works that should more appropriately be called encyclopedias (exampleDictionary of the Middle Ages in 13 volumes). See alsobiographical dictionary and reverse dictionary.

language dictionary lists the words of a language in alphabetical order, giving orthographysyllabication, pronunciation, etymologydefinition, and standard usage. Some dictionaries also include synonyms, antonyms, and brief biographical and gazetteer information. In an unabridged dictionary, an attempt is made to be comprehensive in the number of terms included (exampleWebster's Third New International Dictionary). An abridged dictionary provides a more limited selection of words and usually less information in each entry (Webster's New College Dictionary). In a visual dictionary, each term is illustratedSee alsodesk dictionary and pocket dictionary.

digital archive

A system designed for locating, storing, and providing access to digital materials over the long term. A digital archive may use a variety of preservation methods to ensure that materials remain usable as technology changes, including emulation and migration. The National Digital Information Infrastructure and Preservation Program (NDIIPP) led by the Library of Congress is an example of a program aimed at preserving digital content. Compare with digital archivesSee alsodigital repository

digital archives

Archival materials that have been converted to machine-readable format, usually for the sake of preservation or to make them more accessible to users. A prime example is American Memory, a project undertaken by the Library of Congress to make digital collections of primary sources on the history and culture of the United States available via the Internet. Also refers to information originally created in electronic format, preserved for its archival value (see digital archive).

digital collection

collection of library or archival materials converted to machine-readable format for preservation or to provide electronic access (exampleThe Papers of Thomas Jefferson: Digital Edition, a project of the University of Virginia Library. Also, library materials produced in electronic formats, including e-zines, e-journals, e-books, reference workpublished online and on CD-ROMbibliographic databases, and other Web-based resources. In the United States, the Digital Library Federation is developing standards and best practices for digital collections and network access. In the meantime, the National Information Standards Organization (NISO) has published A Framework of Guidance for Building Good Digital Collections (2007).

digital divide

term coined by former Assistant Secretary of Commerce for Telecommunication and Communication Larry Irving, Jr., to focus public awareness on the gap in access to information resources and services between those with the means to purchase the computer hardware and software necessary to connect to the Internet and low-income families and communities that cannot afford network access. Public libraries are helping to bridge the gap between information "haves" and "have-nots" with the assistance of substantial grants from industry leaders such as Bill Gates of Microsoft. The E-rate established by the Telecommunications Act of 1996 (TCA) has helped schools, public libraries, and rural health care institutions bridge the gap. Digital Divide Network is a Web site devoted to the issue. Synonymous with information gap.

Digital Object Identifier (DOI)

A unique code preferred by publishers in the identification and exchange of the content of a digital object, such as a journal articleWeb document, or other item of intellectual property. The DOI consists of two parts: a prefix assigned to each publisher by the administrative DOI agency and a suffix assigned by the publisher that may be any code the publisher chooses. DOIs and their corresponding URLs are registered in a central DOI directory that functions as a routing system.

The DOI is persistent, meaning that the identification of a digital object does not change even if ownership of or rights in the entity are transferred. It is also actionable, meaning that clicking on it in a Web browser display will redirect the user to the content. The DOI is also interoperable, designed to function in past, present, and future digital technologies. The registration and resolver system for the DOI is run by the International DOI Foundation (IDF). CrossRef is a collaborative citation linking service that uses the DOI. Click here to learn more about the DOI.

digital preservation

The process of maintaining, in a condition suitable for use, materials produced in digital formats, including preservation of the bit stream and the continued ability to render or display the content represented by the bit stream. The task is compounded by the fact that some digital storage media deteriorate quickly ("bit rot"), and the digital object is inextricably entwined with its access environment (software and hardware), which is evolving in a continuous cycle of innovation and obsolescence. Also refers to the practice of digitizing materials originally produced in nondigital formats (printfilm, etc.) to prevent permanent loss due to deterioration of the physical mediumClick here to learn about the National Digital Information Infrastructure and Preservation Program, a collaborative initiative of the Library of Congress. The Digital Preservation Coalition (DPC) was established in 2001 to address the challenges of preserving digital resources in the UK. Synonymous with e-preservation and electronic preservationSee alsodigital archiveLOCKSSNational Digital Information Infrastructure and Preservation Program, and preservation metadata.

digital publishing

The activities involved in the business of preparing, processing, producing, protecting, and preserving information content in digital form, whether the result is delivered in print or electronic format (e-journale-bookWeb document, etc.). In 2005, the Pennsylvania State University Libraries formed a partnership with Penn State Press to create an Office of Digital Scholarly Publishing which will use new media technology to advance scholarly communication at Penn State and within the wider academic community. One goal of the new Office will be to make research publications available online by moving existing print journals and monographs to a digital environment. The role of libraries in digital publishing is discussed by Kate Wittenberg in the article Librarians as Publishers: A New Role in Scholarly Communication in the November/December 2004 issue of Searcher. For a full treatment of the topic, see The Columbia Guide to Digital Publishing edited by William Kasdorf (Columbia University Press: 2003).

digital rights

Ownership of information content published and distributed in electronic format, protected in the United States by copyright law. Digital rights management (DRM) uses technologies specifically designed to identify, secure, manage, track, and audit digital content, ideally in ways that ensure public access, preserve fair use and right of first sale, and protect information producers from uncompensated downloading (copyright piracy).

The Copyright Clearance Center (CCC) provided one of the earliest solutions used by libraries to obtain permissions. Since the late 1990s, a variety of models have emerged to facilitate the complex relationships and transactions among rightsworks, and the parties that produce and use information, including encryption schemes and plug-ins. ContentGuard has based its software approach on XrML (eXtensible rights Markup Language), originally developed at Xerox PARC, which the company hopes will become the open standard for interoperability, giving customers a common platform for receiving content under conditions that protect copyright.

digital rights management (DRM)

A system of hardware and software components and services, designed to distribute and control the rights to intellectual property created or reproduced in digital form for distribution online or via other digital media, in conjunction with corresponding law, policy, and business models. DRM systems typically use data encryptiondigital watermarks, user plug-ins, and other methods to prevent content from being distributed in violation of copyright.

Unfortunately for consumers and libraries, "quick fix" DRM solutions often fail to distinguish between copyright piracy and fair use, may undermine the first sale provision of U.S. copyright law, and can be draconian. For example, many e-book editions completely forbid copying, even for works in the public domain. Carrie Russell, copyright specialist for the American Library Association (ALA), also contends that some DRM solutions threaten "to reduce the functionality of consumer and library electronic equipment, including desktop computers" (Library Journal, August 2003). Click here to learn more about DRM, courtesy of Wikipedia. The Electronic Privacy Information Center (EPIC) provides a Web page on Digital Rights Management and PrivacySee alsoDRM-free.

digital reference

Reference services requested and provided over the Internet, usually via e-mailinstant messaging ("chat"), or Web-based submission forms, usually answered by librarians in the reference department of a library, sometimes by the participants in a collaborative reference system serving more than one institution. For an example, see Ask a librarian... from the Library of Congress. Synonymous with chat referencee-referenceonline referencereal-time reference, and virtual referenceSee alsoMARS: Emerging Technologies in Reference Section.

digital repository

Many academic and research libraries are actively engaged in building digital collections of books, papers, thesesmedia, and other works of interest to the institution served, as a means of preserving and disseminating scholarly information. Usually locally authored or produced, content can be either born digital or reformatted. Access is generally unrestricted, in compliance with the Open Archives Initiative (OAI) protocol for metadata harvesting, which makes such archives interoperable and cross-searchable (see this example maintained by the University of Texas Libraries). Click here to learn more about the role of digital repositories in scholarly communication, courtesy of the Association of Research Libraries (ARL).

direct access

The use of an electronic resource by means of a physical carrier (diskcassettecartridge, etc.) designed to be inserted into a computer or its auxiliary equipment, as opposed to accessing the resource remotely via a network (AACR2). Although disks and CD-ROMs are still used for some applications, most libraries in the United States have shifted to networked digital resources available from vendors on subscription. Compare with remote access.

discard

To officially withdraw an item from a library collection for disposal, a process that includes removing from the catalog all references to it. Also refers to any item withdrawn for disposal, usually stamped "discard" to avoid confusion. Materials are usually withdrawn when they become outdated, cease to circulate, wear out, or are damaged beyond repair. When shelf space is limited, duplicates may be discarded to make room for new acquisitions. Withdrawn items may be exchanged or given as gifts to other libraries, but the most common method of disposal is in a book sale. Unsold items may be given to a thrift store or thrown away as trash, depending on the policy of the library. See alsoweeding.

Depository libraries receiving materials through the Federal Depository Library Program (FDLP) are legally required to retain a federal document for a minimum of 5 years, unless it is a duplicate copy or has been superseded by a more recent editionPublications withdrawn after the 5-year retention period are offered to other depository libraries (see needs and offers). Under Title 44 U.S.Cdocuments that have been offered but not requested by another depository may then be discarded. See alsosuperseded list.

discharge

In circulation, to cancel the record of a loan upon return of the borrowed item and payment of any overdue fine. Compare with chargeSee alsopatron record.

discovery service

A single interface, providing integrated access to the multiple information resources (catalogs, publisherse-book and e-journal collections, subscription databases, archival collections) to which a library has rights. Discovery systems use consolidated subject indexing and metadataSearch results are generally deduped and relevance ranked (exampleEBSCO Discovery Service). For an in-depth discussion of discovery services see the article by William Miller in the March 2012 issue of Library Issues.

document delivery service (DDS)

The provision of published or unpublished documents in hard copymicroform, or digital format, usually for a fixed fee upon request. In most libraries, document delivery service is provided by the interlibrary loan office on a cost-recovery basis. The patron is usually required to pick up printed material at the library, but electronic full-text may be forwarded via e-mail. Also refers to the physical or electronic delivery of documents from a library collection to the residence or place of business of a library user, upon request. Click here to connect to DocDel.net, a directory of document suppliers provided by Instant Information Systems. See alsoAriel and electronic document delivery.

Dublin Core (DC)

A standard set of 15 interoperable metadata elements designed to facilitate the description and recovery of document-like resources in a networked environment.

due date

The date of the last day of the loan periodstamped or written by a library staff member on the date due slip affixed to an item when it is checked out at the circulation deskFines may be charged for materials returned after the due date if they are not renewed. In the online catalog, the due date may be displayed to indicate the circulation status of an item currently checked out. Synonymous with date dueSee alsooverdue.

duplicate publication

published article that substantially duplicates another published article without acknowledgment, both articles having one or more authors in common and a substantial amount of identical text. Duplication may be intentional, often to achieve wider dissemination of the content, especially of a specific type of article, such as a policy statement, or inadvertent through multiple submissions of a manuscript to different journals. In some bibliographic databases, such as MEDLINE, the publication type "Duplicate Publication" may be assigned to a citation with or without formal notification from the author(s) or journal editor, often by an indexer who notices substantial similarity.

 

 

electronic book

digital version of a traditional print book designed to be read on a personal computer or e-book reader. Although the first hypertext novel was published in 1987 (Afternoon, A Story by Michael Joyce), electronic books did not capture public attention until the online publication of Stephen King's novella Riding the Bullet in March 2000. Within 24 hours, the text had been downloaded by 400,000 computer users. Some libraries offer access to electronic books through the online catalog. A universally accepted format and simple delivery system are needed. Click here to browse the Yahoo! list of electronic book sites or try Digital Book Index.

electronic journal

digital version of a print journal, or a journal-like electronic publication with no print counterpart (exampleEJournal), made available via the Webe-mail, or other means of Internet access. Some Web-based electronic journals are graphically modeled on the print version. The rising cost of print journal subscriptions has led many academic libraries to explore electronic alternatives. Directories of electronic journals are available online (exampleEjournal SiteGuide: a MetaSource maintained by the University of British Columbia Library). Synonymous with e-journal. Compare with electronic magazine.
 
electronic magazine
digital version of a print magazine, or a magazine-like electronic publication with no print counterpart (exampleSlate), made available via the Webe-mail, or other means of Internet access. Some Web-based electronic magazines are graphically modeled on the print version (exampleThe New Yorker). MagazineBoard is an example of an online e-magazine directory. Synonymous with e-zine and Webzine. Compare with electronic journal.

electronic publication

work in digital form capable of being read or otherwise perceived, distributed to the general public electronically. The category includes electronic journals and e-prints, electronic magazines and newspapers, electronic books, Web sites, Weblogs, etc. Some electronic publications are online versions of print publications; others are born digital. Synonymous with e-publication.

electronic publishing

The publication of books, periodicals (e-journals, e-zines, etc.), bibliographic databases, and other information resources in digital format, usually on CD-ROM or online via the Internet, for in-house users, subscribers, and/or retail customers, with or without a print counterpart (exampleJournal of Electronic Publishing (JEP)). Synonymous in this sense with e-publishing. Also used synonymously with desktop publishing.

electronic records

Bibliographic or archival records stored on a medium, such as magnetic tape/disk or optical disk, that requires computer equipment for retrieval and processing. Compare with machine-readable records.

electronic resource

Material consisting of data and/or computer program(s) encoded for reading and manipulation by a computer, by the use of a peripheral device directly connected to the computer, such as a CD-ROM drive, or remotely via a network, such as the Internet (AACR2). The category includes software applications, electronic texts, bibliographic databases, institutional repositoriesWeb sites, e-books, collections of e-journals, etc. Electronic resources not publicly available free of charge usually require licensing and authenticationAbbreviated e-resourceSee alsoelectronic resources management.

electronic resources management (ERM)

Systems developed to assist librarians in the control of licensed third-party resources published electronically (databases, e-books, e-journals, etc.), including license management, renewal, legal use, access management, and collection development. In 2001, a small group of academic librarians began to create metadata specifications for managing electronic subscriptions and their associated titles. The group was later asked by the Digital Library Federation (DLF) to deliver formal specifications for vendors, as a replacement for various homegrown systems. Innovative Interfaces Inc. was the first library automation vendor to market an ERM software module based on the DLF specifications, and other vendors have followed suit. Compare with digital asset management.

electronic rights

The right to publish and sell copyright-protected material in electronically accessible form, for example, on CD-ROM or online via the Internet. Electronic rights are negotiated with the publisher and should be clearly stated in the author's contractClick here to read what the Authors Guild has to say about electronic rights. Abbreviated e-rights.

enumeration

A naming or counting of items, one by one, as in a list, in any amount of detail but without systematic arrangement. Also, the volume numbering of a serial issueSee alsoenumerative classification.

enumerative classification

classification system in which each subject is developed to the point of indivisibility and a notation assigned for every subdivision (exampleLibrary of Congress Classification). Compare with synthetic classificationSee alsohierarchical classification.

environmental control

In the preservation of library and archival collections, creating and maintaining hospitable storage conditions is the most effective strategy for promoting the longevity of materialsDeterioration of paperleathercloth, plastic, etc., can be dramatically reduced by controlling temperature, relative humiditylight, and air quality in storage. Monitoring devices should be installed to ensure that materials remain cool and dry. Low illumination, ventilation that removes atmospheric pollutants, and effective pest management are also essential. Click here to read Oxford University Library Services' advice on environmental monitoring and control.

e-print

preprint in digital format, distributed electronically. The use of e-print servers to provide access to collections of preprints is a comparatively new mode of scholarly communication, developed in the physical sciences to circumvent the delays and high cost of commercial publishing. One of the earliest and best-known e-print repositories was created at the Los Alamos National Laboratory in New Mexico. The Open Archives Initiative (OAI) aims to facilitate the retrieval of scholarly papers from disparate digital archives. Also spelled eprint.

export edition

An edition of a publication prepared by the publisher specifically for distribution or sale in another country (or countries). Compare with co-edition.

extended subscription

Instead of resupplying claimed issues or parts, or issuing a credit, the publisher of a periodical may compensate the subscriber by lengthening the period of the current subscription.
 

fair copy

In publishing, the final version of the manuscript or typescript of an original work, containing few mistakes and no corrections, having been carefully prepared from the final draft by the author, or by a copy editor, for the use of the printerClick here to see the autograph fair copy of a concerto by Mozart (Cornell University Library). Synonymous with clean copy.

fair use

Conditions under which copying a work, or a portion of it, does not constitute infringement of copyright, including copying for purposes of criticism, comment, news reporting, teaching, scholarship, and researchClick here for more information about Copyright & Fair Use provided by the Stanford University Libraries.
U.S. Copyright Act: Fair Use

Title 17. Chapter 1. Section 107. Limitations on exclusive rights: Fair use

Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is fair use the factors to be considered shall include:

(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;

(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work.

The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.

first published edition

An edition issued for sale to the general public after the work has been distributed to a restricted audience, for example, a motion picture released for public viewing after it has been previewed by a limited audience, usually persons invited by the producer.

full-text

An electronic resource that provides the entire text of a single work (exampleBritannica Online) or of articlepublished in one or more journals, magazines, and/or newspapers. For example, a bibliographic database that provides the complete text of a significant proportion of the works indexed, in addition to the bibliographic citation and (in many cases) an abstract of the content (exampleJSTOR). Also spelled full text and fulltext.

full-text search

search of a bibliographic database in which the entire text of each record or document is searched and the entry retrieved if the terms included in the search statement are present. Most Web search engines are designed to perform full-text searches. This can pose a problem for the user if a search term has more than one meaning, resulting in the retrieval of irrelevant information (false drops). For example, in a medical database, the query "treatment of AIDS" might retrieve entries for sources containing the phrase "treatment aids in geriatrics" (with "of" a stopword). Compare with free-text search.

federated search

search tool designed to query multiple networked information resources via a single interface (exampleGoogle Scholar). The metasearch engines developed in the second half of the 1990s were capable of searching only publicly accessible Web sites, but the 21st century has seen a new generation of federated search engines designed to search local and remote library catalogs, subscription databases, and digital repositories as well as Web sites, using standardized protocols, such as Z39.50. Some federated search systems provide deduping and rank results by relevance or allow sorting by other criteria. Limiting, advanced search modes, clustering, and RSS feeds or search alerts may also be available.
 

gap

A set of issues or entire volumes missing from a library's holdings of a serial title. This can occur when a subscription is canceled and later resumed or when items are lost or stolen. Most libraries try to fill gaps in periodical subscriptions with microfilm or microfiche, or by relying on the services of a back issuedealer, when online full-text is not available. Compare with nongap break.

gate count

The number of times a mechanical counting device, located at the entrance to or exit from a library, is automatically activated whenever a person enters or leaves during a designated period of time (day, week, month, year), an important measure of library use. In most facilities, the counter is located near, attached to, or part of the security gate. Totals are recorded at regular intervals, usually by the staff at the circulation desk. Gate counts provide statistical information on traffic patterns, helpful in establishing library hours and anticipating staffing needs. Synonymous with door count.

geographic index

An index in which the entries are listed by their geographic location (city, state, country, etc.). Also refers to an index that lists the geographic locations mentioned in the text of a document. Synonymous with place indexSee alsogazetteer.

gray literature

Documentary material in print and electronic formats, such as reports, preprints, internal documents (memorandanewsletters, market surveys, etc.), theses and dissertations, conference proceedings, technical specifications and standards, trade literature, etc., not readily available through regular market channels because it was never commercially published/listed or was not widely distributed. Such works pose challenges to libraries in identification (indexing is often limited) and acquisition (availability may be uncertain). Absence of editorial control also raises questions of authenticity and reliability. Alternative methods of supply and bibliographic control have evolved in response to the need to preserve and provide access to such material. In the United States, the gray literature of science and technology is indexed in the NTIS database. Theses and dissertations are indexed and abstracted in Dissertation Abstracts International and are available in hard copy via Dissertation ExpressClick here to learn more about finding gray literature, or see the article Gray Literature: Resources for Locating Unpublished Research by Brian S. Mathews in the March 2004 issue of C&RL News. Also spelled grey literature. Compare with ephemera and fugitive materialSee alsosemipublished.
 

handbook

A single-volume reference book of compact size that provides concise factual information on a specific subject, organized systematically for quick and easy access. Statistical information is often published in handbook form (exampleStatistical Handbook on the American Family). Some handbooks are published serially (CRC Handbook of Chemistry and Physics). Synonymous with vade mecumSee alsocompanion and manual.

handout

printed sheet or group of sheets, usually stapled together at one corner, intended for distribution during an oral presentation or instruction session to give the attendees a record of content covered (summaryoutlinehard copy of PowerPoint slides, etc.) or to provide supplementary or complementary information (supporting data, examples, suggestions for further reading, contact information, etc.).

holdings

The total stock of materialsprint and nonprint, owned by a library or library system, usually listed in its catalog. Synonymous in this sense with library collection.

holdings record

In cataloging, a separate record attached to the bibliographic record for a serial title or multivolume item to track issues, parts, volumes, etc., as they are acquired by the library. A format for holdings is defined in MARC 21. In most libraries, the holdings record is separate from the check-in record used for current receipts of serials. As successive issues or parts are received and volumes are completed, the record of receipt is moved from the check-in record to the holdings record. Compare with item record.
 

impact factor

In citation analysis, a quantitiative measure of the frequency with which the "average articlepublished in a given scholarly journal has been cited in a particular year or period, developed by the Institute for Scientific Information (ISI) for use in Journal Citation Reports, a multidisciplinary tool for ranking, evaluating, and comparing journals within subject categories. The indicator is used by seriallibrarians in collection management, journal publishers in marketing, information analysts in bibliometric research, and authors to identify journals in which to publish. Caution is advised in using the indicator as a measure a journal's prestige for purposes of academic evaluation for tenure or promotion.

imprint

The statement in a book that identifies the publisher and/or printer. The publisher's imprint consists of the official name of the publishing company and the date and place of publication. It usually appears at the foot of the title page and more completely on the verso of the title page. The printer's imprint, indicating the name of the printing company and the place of printing, usually appears on the verso of the title page, at the foot of the last page of text, or on the page following the text. By extension, the printed or published item itself, as in "early 19th-century imprint." Synonymous with biblioSee alsocolophondistribution imprinteponymous imprintfictitious imprintjoint imprint, and personal imprint.

In binding, the name of the publisher and/or the publisher's device stamped at the base of the spine, or the name of the binder stamped on the inside of the back board of the cover, usually near the bottom.

information desk

A desk in a large public or academic library, usually located near the main entrance, staffed by a nonprofessional trained to screen questions, provide basic information about library services and collections, and direct users to the reference desk or some other public service point, when further assistance is needed. The presence of an information desk reduces the number of directional questions received by reference librarians, freeing them to focus on the needs of patrons who require professional services. Units within a library may also have an information desk (see this example at the Kent State University).

information system (IS)

A computer hardware and software system designed to accept, store, manipulate, and analyze data and to report results, usually on a regular, ongoing basis. An IS usually consists of a data input subsystem, a data storage and retrieval subsystem, a data analysis and manipulation subsystem, and a reporting subsystem. Widely used in scientific research, business management, medicine and health, resource management, and other fields that require statistical reporting, information systems can be broadly classified as spatial or nonspatial, depending on whether the data refers to a system of spatial coordinates. See alsogeographic information systemmanagement information system, and spatial information system.

information technology (IT)

A very broad term encompassing all aspects of the management and processing of information by computer, including the hardware and software required to access it. The Library and Information Technology Association (LITA) publishes the quarterly journal Information Technology and Libraries (ITAL). See also Current Cites, an annotated bibliography of selected articles, books, and digital documents on information technology, edited by Roy Tennant of the California Digital Library.

information theory

The systematic statement of principles concerning the phenomenon of information and its transmission, based on the collection and analysis of quantitative and qualitative data as a means of testing hypotheses about its nature and properties. Compare with informatics.

in-house training

Instruction conveniently given to library staff at their place of employment, for example, in a webcast, as opposed to training given at a remote location.

initial article

An article appearing in first-word position in a title or corporate name, usually aan, or the (or the equivalent in another language), ignored in indexing and filing under most filing rules. See alsononfiling character.

institutional repository (IR)

A set of services offered by a university or group of universities to members of its community for the management and dissemination of scholarly materials in digital format created by the institution and its community members, such as e-prints, technical reports, theses and dissertations, data sets, and teaching materials. Stewardship of such materials entails their organization in a cumulative, openly accessible database and a commitment to long-term preservation when appropriate. Some IRs are also used as electronic presses to publish e-journals and e-books. An institutional repository is distinguished from a subject-based repository by its institutionally defined scope. IRs are part of a growing effort to reform scholarly communication and break the monopoly of journal publishers by reasserting institutional control over the results of scholarship. An IR may also serve as an indicator of the scope and extent of the university's research activities. For an example, see the Caltech Collection of Open Digital Archives (CODA).

integrated access

An information retrieval system that allows users to search for books, periodical articles, and electronic resources such as computer files and Web sites, in one operation using a single interface, instead of searching online catalogs, bibliographic databases, and Web search engines separately. Seamless access is a goal that remains to be realized in most libraries.

intellectual property

Tangible products of the human mind and intelligence entitled to the legal status of personal property, especially works protected by copyright, inventions that have been patented, and registered trademarks. An idea is considered the intellectual property of its creator only after it has been recorded or made manifest in specific form. Abbreviated IPSee alsoinformation law.

interlibrary loan (ILL)

When a book or other item needed by a registered borrower is checked outunavailable for some other reason, or not owned by the library, a patron may request that it be borrowed from another library by filling out a printed interlibrary loan request form at a service desk, or electronically via the library's Web site. Some libraries also accept ILL requests via e-mail or by telephone, usually under exceptional circumstances. Materials borrowed on interlibrary loan may usually be renewed on or before the due date.

Interlibrary loan is a form of resource sharing that depends on the maintenance of union catalogs. The largest interlibrary loan network in the world is maintained by OCLC, which uses the WorldCat database as its union catalog. The Reference and User Services Association (RUSA) of the American Library Association (ALA) has developed an Interlibrary Loan Code for the United States (2008). Compare with document delivery service and intralibrary loanSee alsoArielborrowing libraryfill ratelending library, and reciprocal agreement.

International Standard Book Number (ISBN)

A unique ten-digit standard number assigned to identify a specific edition of a book or other monographic publication issued by a given publisher, under a system recommended for international use by the International Organization for Standardization (ISO) in 1969. In the ISBN system, media such as audiorecordings, videorecordings, microfiche, and computer software are considered monographic publications, but serials, music sound recordings, and printed music are excluded because other identification systems have been developed to cover them. The ISBN is usually printed on the verso of the title page and on the back of the dust jacket of a book published in hardcover, or at the foot of the back cover in paperback editions. In AACR2, the ISBN is entered in the standard number and terms of availability area of the bibliographic description.

International Standard Serial Number (ISSN)

A unique eight-digit standard number assigned by the International Serials Data System (ISDS) to identify a specific serial title, for example, 0363-0277, identifying the publication Library Journal. In 2001, the scope of the ISSN was extended to cover continuing resources in general. The ISSN is usually given in the masthead of each issue or on the copyright page of each volume or part of a series. When a continuing resource undergoes a title change, a new ISSN is assigned. In library cataloging under AACR2, the ISSN is entered in the standard number and terms of availability area of the bibliographic description. The ISSN International Centre located in Paris, France, maintains a Web site at: www.issn.org. Compare with local serial control numberSee alsoInternational Standard Book Number and ISSN-L.
 

joint author

In AACR2, a person who collaborates with one or more others to produce a work in which all who contribute perform the same function. The contributions of the individual collaborators may not be indicated and are usually not separable. In catalogingmain entry is made under the name of the author listed first on the chief source of information (the primary author), with added entries for the other authors, unless primary responsibility clearly rests with one author. Bibliographic style manuals differ in the maximum number of joint authors included in a citation. Synonymous with coauthor. Compare with composite workSee alsoet al. and shared responsibility.
 

key title

The unique name assigned to a serial publication by the centers of the ISSN Network under the International Serials Data System (ISDS), usually (but not always) the same as the title proper. In library cataloging, the key title is entered immediately following the ISSN in the bibliographic record. If there is no ISSN, the key title is not added. Also spelled key-title.

kiosk

A small circular pavilion, usually located near the entrance to a library, used for displaying announcements, dust jackets removed from new books, reading lists, comments and suggestions from library users (sometimes with responses from library administration), and other information concerning library operations and programs. See alsobulletin board.

Also refers to a free-standing furnishing equipped with a multimedia computer to allow users to retrieve information "on the run" via a touchscreen, used in airports and other public locations to provide directions, scheduling information, etc.

 

large paper edition

An edition printed from the same setting of type as the trade edition but on leaves of larger size (and usually paper of superior quality), making the margins wider than normal. Limited and deluxe editions are often printed in this way. Compare with large paper copy.

lead-in title

Backlisted titles offered in a book club mail advertising campaign at very low prices or no charge, as an inducement to potential subscribers or as bonuses or dividends to existing members. Synonymous with introductory title.

library card

A small paper or plastic card issued by a library in the name of a registered borrower, to be presented at the circulation desk when checking out materials from its collections. Identification is usually required of new applicants. In most libraries in the United States, library cards are barcoded for electronic circulation (see this example). Periodic renewal may be required to verify contact information (current street address and telephone number). Synonymous with borrower cardSee alsolibrary card campaign and patron ID.

library tour

A guided walk through a library facility, usually conducted by a librarian or library assistant, to orient new users to the location of services and resources. Some libraries have installed online or "virtual" library tours on their Web sites, which may include clickable floor planlinked to photographs and descriptive text (see this live example from the South Piedmont Community College Library, NC). Not to be confused with bibliographic instruction.

licensed book

book in which the author makes use of a character or product subject to copyright restrictions, for example, a children's book based on a motion picture character (Mickey Mouse) or a commercially successful toy (Barbie). Use is by permission of the copyright holder under the terms of a licensing agreement handled by the copyright owner's licensing agent. Although the sales potential of licensed books makes them popular with retail booksellers, they are generally not purchased for library collections

loan rule

In library circulation systems, the decision governing the prescribed period of time for which an item of a specific item type may be checked out by a borrower, depending on the patron type. The loan rule also determines the form of the notice sent when an item is kept past its due date and the amount of any overdue fine charged to the patron. The cost of replacing a lost or damaged item may also be determined in part by the loan rule. Each library or library system establishes and maintains its own set of loan rules for the various categories of materials in its collections.

loan status

The type of loan in effect at a particular time for a specific item in a library collection. In public and academic libraries, most items are available for general circulation, but some may be on reserve or on loan to other libraries via interlibrary loanNoncirculating items such as reference books are for library use only.
local author
published writer who lives in the geographic area served by a library. Once rare but increasing in numbers with the growing popularity of self-publishing, local authors may actively court libraries to promote their works. They are sometimes invited to participate in library programs. Local authorship can be a criterion for selection, if demand exists, but some libraries are adopting policies for collecting self-published works which require reviews in established review journals.

local bibliography

bibliography of books and other materials about a specific geographic area smaller than a country, usually covering material about the history, geography, architecture, and environment of the area, as well as works about the people born or residing in it. Useful in genealogical researchSee alsoregional book.

local collection

library collection of books, prints, maps, photographs, and other materials related to a specific geographic area and its inhabitants, usually the community in which the library is located, useful in historical and genealogical researchSee alsolocal bibliography and regional book.
 

Machine-Readable Cataloging (MARC)

An international standard digital format for the description of bibliographic items developed by the Library of Congress during the 1960s to facilitate the creation and dissemination of computerized cataloging from library to library within the same country and between countries. By 1971, the MARC format had become the national standard for dissemination of bibliographic data and by 1973, an international standard.

There are several versions of MARC in use in the world, the most predominant being MARC 21, created in 1999 as a result of the harmonization of U.S. and Canadian MARC formats, and UNIMARC, widely used in Europe. The MARC 21 family of standards now includes formats for authority records, holdings records, classification schedules, and community information, in addition to formats for the bibliographic record.

magnetic stripe

In a composite print of a motion picture, the thin coating of magnetic oxide capable of carrying the sound track, applied in a narrow band along the film edge and on some films to the opposite edge as a balance stripe when the film is wound on a reel or core. Also used synonymously with data stripAbbreviated magstripe.

magnetic tape

An electronic storage medium consisting of a thin strip of flexible plastic to which a metallic coating is applied that can be selectively magnetized to record information sequentially in linear or helical tracks. Magnetic tape is mounted on open reels or in cartridges. To retrieve a specific record or file on tape, all the records (or partitions) preceding it must be sequentially searched. Magnetic disk storage is faster because it allows data to be accessed randomly. For this reason, data in current use is usually stored on disk, but tape is often used for archival storage because it is more economical and has greater capacity. Click here to learn more about how tape recorders work, courtesy of HowStuffWorks.

metadata

Literally, "data about data." Structured information describing information resources/objects for a variety of purposes. Although AACR2/MARC cataloging is formally metadata, the term is generally used in the library community for nontraditional schemes such as the Dublin Core Metadata Element Set, the VRA Core Categories, and the Encoded Archival Description (EAD). Metadata has been categorized as descriptivestructural, and administrativeDescriptive metadata facilitates indexingdiscovery, identification, and selection. Structural metadata describes the internal structure of complex information resources. Administrative metadata aids in the management of resources and may include rights management metadata, preservation metadata, and technical metadata describing the physical characteristics of a resource. For an introduction to metadata, please see Priscilla Caplan's Metadata Fundamentals for All Librarians (American Library Association, 2003). Also spelled meta-dataSee alsoMetadata Encoding and Transmission Standard and Metadata Object Description Schema.

metadatabase

database of databases, usually formed by aggregating two or more smaller databases to allow the user to search their contents as a whole, instead of repeating the same search in each separately (exampleOneFile from Gale, which consolidates the InfoTrac bibliographic databases into a single, very large finding tool). The pace of aggregation has accelerated as very large vendors have dominated the market for access to periodical databases, but however helpful "one-stop searching" may be in interdisciplinary research (and to users who lack the skill to select the optimum databases for a specialized topic), segmentation still offers significant advantages for the experienced researcher.

methods journal

A scholarly periodical devoted to disseminating information about the development of new techniques in scientific research and the refinement of existing methodologies (example: the biweekly Journal of Immunological Methods).

mirror site

An exact copy of a Web site, installed on a server other than the one maintained by the official host, usually to handle demand for the site's content in another country or region. When the main server goes offline, the Web site it normally hosts may still be available at one or more mirror sites.

missing copy

Parts of a book, such as the index or appendices, that may not be ready when a publisher sends the typescript and specifications to the printer. If additional copy is to follow, allowance must be made in estimating the cost of printing.

missing issue

An issue of a newspaper or periodical not received by a library subscriber within a specified period of time, or after a designated number of claims, as distinct from an issue lost or stolen following receipt and check-in. The publisher or vendor may offer an extended subscription in compensation. The library may eventually fill the gap by purchasing a replacement from a back issuedealer.

multiple editions

In publishing, a book available at the same time in more than one edition, for example, the original trade edition, a movie or television tie-in (usually in mass market or trade paperback), and a special anniversary edition. When two editions of the same title are available at the same time, they are known as dual editions.

multiple user access

file of data that can be used independently by more than one person at the same time, for example, a multivolume print encyclopedia as opposed to a single-volume dictionaryAccess to online catalogs, bibliographic databases, and full-text electronic resources by more than one simultaneous user may be governed by licensing agreement. Compare with multiple access.
 

national bibliography

An ongoing list of the books and other materials published or distributed in a specific country, especially works written about the country and its inhabitants or in its national language, for example, Canadiana and the British National Bibliography (BNB), which since 1950 has provided a weekly list of new titles published in Great Britain. The focus of national bibliography has traditionally been print materials (books, serials, pamphlets, maps, printed music, government documents, etc.), but nonprint media including works created in digital formats are also listed in some countries.

As noted in the International Encyclopedia of Information and Library Science (Routledge, 2003), current national bibliography was originally undertaken by the book trade to facilitate commerce (as exemplified by the Cumulative Book Index in the United States) but since the early 1950s, the regular listing of new publications has been regarded as the proper function of a national agency, usually operating within the national libraryRetrospective national bibliography has been accomplished in part by publication of the catalogs of the national library, based on collections established by copyright deposit. Projects such as the English Short Title Catalogue (ESTC) have extended retrospective bibliography beyond the holdings of national libraries.

For a non-English language example, see the National Bibliography of Indian Literature, 1901-1953 (NBIL), digitized by the Center for Research Libraries as part of its Digital South Asia Library project.

 

on-demand publishing

Production by a commercial service of single copies or small quantities of rareout of print, or difficult to find publications in response to orders from individual customers, as opposed to supply from inventory. An example of such a service is Dissertation Express from ProQuest, which provides photocopy reproductions of Ph.D. dissertations made to order from microform masters for a fixed fee. On-demand publishing is expected to grow, especially to meet sci-tech and business needs, as digital archives expand. Synonymous with demand publishing.

online catalog

library catalog consisting of a collection of bibliographic records in machine-readable format, maintained on a dedicated computer that provides uninterrupted interactive access via terminals or workstations in direct, continuous communication with the central computer. Although the software used in online catalogs is proprietary and not standardized, most online catalogs are searchable by authortitlesubject heading, and keywords, and most public and academic libraries in the United States provide free public access, usually through a Web-based graphical user interfaceClick here to log on to the online catalog of the Library of Congress in Washington, D.C. Synonymous with OPAC.

online services

In libraries, the branch of public services concerned with selecting and providing access to electronic resources, such as online catalogs and bibliographic databases, including mediated searching, often handled by an online services librarian. Compare with systems librarian.

OPAC

An acronym for online public access catalog, a database composed of bibliographic recorddescribing the books and other materials owned by a library or library systemaccessible via public terminals or workstations usually concentrated near the reference desk to make it easy for users to request the assistance of a trained reference librarian. Most online catalogs are searchable by authortitlesubject, and keywords and allow users to printdownload, or export records to an e-mail account. Compare with WebPacSee alsoMachine-Readable Cataloging.

open access

Information content made freely and universally available via the Internet in easy to read format, usually because the publisher maintains online archives to which access is free or has deposited the information in a widely known open access repository. Open access is a new model of scholarly publishing developed to free researchers and libraries from the limitations imposed by excessive subscription price increases for peer-reviewed journals, particularly in the sciences and medicine. By breaking the monopoly of publishers over the distribution of scientific research, open access makes access to scientific information more equitable and has the added advantage of allowing the author to retain copyrightSee alsoFederal Research Public Access Actopen access journalopen access reference workOpen Archives Initiative, and Scholarly Publishing and Academic Resources Coalition.

open access journal

A scholarly periodical that makes the full text of the articles it publishes universally and freely available via the Internet in easily read format, in some cases by depositing them immediately upon publication without embargo in at least one widely recognized open access repository. In this new model of scholarly communication, the costs of publication are recovered not from subscription fees, but from publication fees paid by authors out of their grant funds or from other sources. The first open access peer-reviewed journal, the monthly PLoS Biology, was first issueonline in October 2003 by the Public Library of Science (PLoS), a nonprofit organization of scientists and physicians.

BioMed Central (BMC) is an example of an independent commercial publisher committed to providing immediate open access to peer-reviewed research. Its charter states that, "The author(s) or copyright owner(s) irrevocably grant(s) to any third party, in advance and in perpetuity, the right to use, reproduce or disseminate the research article in its entirety or in part, in any format or medium, provided that no substantive errors are introduced in the process, proper attribution of authorship and correct citation details are given, and that the bibliographic details are not changed." See the SPARC Open Access Newsletter (SOAN) for the latest developments on open access e-journals. A Directory of Open Access Journals (DOAJ) is provided by the Lund University Libraries. See alsoOpen Archives Initiative.

open access repository

digital archive created and maintained to provide universal and free access to information content in easily read electronic format as a means of facilitating research and scholarship. A prime example is PubMed Central (PMC), a project of National Center for Biotechnology Information at the U.S. National Library of Medicine, designed to provide open access to the journal literature of the life sciences. See alsoopen access journal and Open Archives Initiative.

Open Archives Initiative (OAI)

An organization funded by the Digital Library Federation, the Coalition for Networked Information, and the National Science Foundation to develop and promote interoperability standards as a means of facilitating the exchange of digital information content. Its program originated in the desire to advance scholarly communication by improving access to distributed repositories of e-prints, known as "archives." The main product of the OAI is a framework for harvesting and aggregating metadata from multiple repositories and a harvesting protocol known as the OAI Protocol for Metadata Harvesting (OAI-PMH)Click here to learn more about OAI. See alsoopen access and Scholarly Publishing and Academic Resources Coalition.

open catalog

library catalog in which there are no restrictions on the addition of new bibliographic records, and existing records are revised and corrected as the need arises. Compare with closed catalog and frozen catalog.

OpenURL

A framework and format for communicating bibliographic information between applications over the Internet. The information provider assigns an OpenURL to an Internet resource, instead of a traditional URL. When the user clicks on a link to the resource, the OpenURL is sent to a context-sensitive link resolution system that resolves the OpenURL to an electronic copy of the resource appropriate for the user (and potentially to a set of services associated with the resource). The OpenURL shows promise of becoming an important tool in the interoperation of distributed digital library systems and has the potential to change the nature of linking on the Web.

The OpenURL was conceived at the University of Ghent by Herbert Van de Sompel and Patrick Hochstenbach, and by Oren Beit-Arie of the Ex Libris library automation company, who built a resolution system called SFX, now licensed to Ex Libris. SFX is being used by NISO to draft a U.S. national standard for OpenURL that will be compatible with other standards such as MARC 21Dublin CoreOnline Information Exchange (ONIX), and the Open Archives Initiative (OAI).

out of circulation

Not available to be checked out or used for reference, for example, library materials in the process of being mendedrepaired, reboundrecataloged, etc. The opposite of in circulation. Compare with noncirculating.

out of print (OP)

publication no longer obtainable through regular market channels because the publisher's inventory is exhausted, with no prospect of another printing in the foreseeable future. A book goes out of print when the publisher decides sales no longer justify the expense of maintaining inventory, when it is superseded by a later edition, or when the rights are relinquished by the publisher.

An OP title can sometimes be located in a used bookstores. Search services, antiquarian booksellers, and book scoutspecialize in tracking down out of print editions (examplesAbebooks and Alibris). An out of print book may eventually be reissued (the review publication Library Journal includes a "Classic Returns" section devoted to recent reprints). Books that have gone out of print since 1979 are indexed in Books Out-of-Print published by Bowker, which includes information on remainder dealers and on-demand publishers. Also spelled out-of-print. Also abbreviated o.p. Compare with out of print at presentout of stock, and temporarily out of print.

overdue

circulating item checked out from a library and kept by the borrower past its due date. Most circulation systems are designed to automatically generate an overdue notice requesting prompt return of the item. Many libraries in the United States charge fines for overdue materials. A borrower account may be blocked if fines accumulate beyond a maximum amount determined by the library. Accounts long overdue may be sent to a collection agency. Overdue charges can be avoided by renewing the item on or before its due date. See alsograce period.

overdue notice

printed or handwritten notice sent to a borrower's street address requesting the prompt return of items kept past their due date. The first overdue notice may be followed by a second notice, then a final notice, depending on the policy of the individual library or library systemSee alsofines and renew.
 

patron

Any person who uses the resources and services of a library, not necessarily a registered borrower. Synonymous with user. Compare with clientSee alsopatron IDpatron recordpatron type, and problem patron.

Also, a person who helps sponsor the creation, copying, or printing of an original work. In medieval Europe, the patron who commissioned a manuscript was sometimes depicted in a presentation miniature or other illustration in the work. See Simon de Varie kneeling in prayer in his Book of Hours (Getty Museum, MS 7) and James IV of Scotland using his prayer book (Getty Museum). During the 16th and 17th centuries, when returns from the fees paid by printer/publishers were meager, many writers could not have flourished without the patronage of wealthy individuals and institutions. It was not unusual for a sponsored work to be formally dedicated to the benefactor, in gratitude and hope of further financial assistance.

In a more general sense, any person or group that encourages or supports an activity, project, or institution such as a library, especially by providing funds or other material resources.

patron ID

The means by which staff at the circulation desk of a library ascertain that a patron is a registered borrower, usually the person's library card, student ID card, security badge, or a substitute. Also refers to the number used in most library circulation systems to identify the borrower. Sometimes it is the library card number, but in academic libraries it may be the student ID number or the social security number. In special libraries, patron ID may be linked to the employee identification system used by the parent organization. Each library or library system adopts its own method of patron identification. See alsopatron record.

patron profile

A description of the behavior and preferences of a library's users, or of a specific category of library patron (adults, young adults, children), usually based on systematically collected and analyzed survey data, for use in planning. Library Journal publishes the online quarterly Patron Profiles.

patron record

confidential record in a library circulation system containing data pertinent to a borrower account (full name, street address, telephone number, patron IDpatron type, items on loan, holds, unpaid fines, etc.). In electronic circulation systems, an authorized member of the library staff is permitted to access the patron record by scanning the barcode on the library card or by using a keyboard to enter the patron's name or library card number as input. Some online catalogs allow registered borrowers to view thir own patron records with proper authorization. Synonymous with circulation recordSee alsoblocked.

patron type

In library circulation systems, a code entered in the patron record to indicate a specific category of borrower, which in conjunction with item type determines the loan rule applied when an item is checked outAcademic libraries usually differentiate faculty, student, alumni, and staff by patron type. Most public libraries distinguish between nonresidents and patrons who reside within the service area and between adult and juvenile users. In special libraries, patron type may reflect hierarchical rank within the parent organization, levels of security clearance, etc.

peer review

The process in which a new bookarticlesoftware program, etc., is submitted by the prospective publisher to experts in the field for critical evaluation prior to publication, a standard procedure in scholarly publishing. Under most conditions, the identity of the referees is kept confidential, but the identity of the author(s) is not. The existence and content of a manuscript under review is kept confidential within the offices of the publisher and by the referees, and all copies of the manuscript are returned to the publisher at the end of the process. In computer programming, source code may be certified by its owner or licenser as open source to encourage development through peer review. Synonymous with juried review.

Also refers to a method of performance evaluation in which the quality of a worker's job performance is assessed by the employee's peers within the organization, usually as part of a formal review process resulting in a recommendation to management.

peer-reviewed

Said of a scholarly journal that requires an article to be subjected to a process of critical evaluation by one or more experts on the subject, known as referees, responsible for determining if the subject of the article falls within the scope of the publication and for evaluating originality, quality of research, clarity of presentation, etc. Changes may be suggested to the author(s) before an article is finally accepted for publication. In evaluation for tenure and promotionacademic librarians may be given publishing credit only for articles accepted by peer-reviewed journals. Some bibliographic databases allow search results to be limited to peer-reviewed journals. Synonymous with juried and refereed.

period bibliography

bibliography limited to works covering a specific period of time, for example, American history of the colonial period or the progressive era.

periodical

serial publication with its own distinctive title, containing a mix of articles, editorials, reviews, columns, short storiespoems, or other short works written by more than one contributor, issued in softcover more than once, generally at regular stated intervals of less than a year, without prior decision as to when the final issue will appear. Although each issue is complete in itself, its relationship to preceding issues is indicated by enumeration, usually issue number and volume number printed on the front coverContent is controlled by an editor or editorial board.

The category includes magazines, sold on subscription and at newsstands; journals, sold on subscription and/or distributed to members of scholarly societies and professional associations; and newsletters, but not proceedings or the other regular publications of corporate bodies as they relate primarily to meetings. Nor are newspapers formally classified as periodicals--although many libraries store newspapers with magazines and journals, separate values are assigned for periodicals and newspapers in the 008 field of the MARC record to indicate type of serial. Also, the statement in AACR2 that serials include periodicals, newspapers, annuals, proceedings, and numbered monographic series implies that newspapers are not considered periodicals.

popular edition

An edition of a book printed on poorer-quality paper than the trade edition, sometimes without illustrations and in a less sturdy cloth or softcover binding, usually sold at a lower price. Some book club editions fall into this category.

preference order

In Dewey Decimal Classification, the order in which one of two or more numbers is to be chosen when different characteristics of a subject cannot be shown in full by number building, indicated in a note, sometimes containing a table of preference (DDC). When the class notation can be synthesized to show two or more characteristics, the decision is governed by citation order. Synonymous with order of preference and precedence order.

preprint

A portion of a work printed and distributed for a special purpose in advance of the publication date announced for the whole, for example, an article to be published in a periodical or a work selected for inclusion in an anthology or collection. Also, a paper prepared for presentation at a conference, printed in multiple copies in advance of the conference date, usually for distribution to participants and other interested persons. In some academic disciplines, preprints are an important medium of scholarly communication. Also refers to a few copies of an author's manuscript produced by a method such as xerography for circulation within the office of the publisher, usually to facilitate reading, evaluation, and editingSee alsoe-print.

Also refers to an advertising insert printed by a manufacturer to be included in a periodical, sometimes designed to accommodate local copy, such as the names and addresses of sales outlets located in the area of circulation.

press clipping service

An organization in the business of collecting copies of reviews, articles, columns, photographs, etc., published in newspapers and magazines about authors, prominent people, news events, or other topics of interest to clients who pay a fee to receive them on a regular basis. The Yahoo! Directory provides a list of press clipping and monitoring services.

proxy server

An application program that operates between a client and server on a computer network, usually installed as a firewall to provide security or to increase speed of access by performing some of the housekeeping tasks that would normally be handled by the server itself, such as checking authentication or validating user requests. Also called a proxySee alsodaemon and EZproxy.
 

ready reference

reference question that can be answered by a reference librarian in one or two minutes by providing a fact or piece of information found in a single source. However, upon further inquiry, what at first appeared to be a simple query may turn out to be an opening gambit in a more extensive search, once the nature of the information need is fully understood.

Also refers to the reference materials used most often in answering such questions, shelved for convenience in a separate location near the reference desk rather than in the reference stacks (Books in PrintEncyclopedia of AssociationsStatistical Abstract of the U.S., world almanacs, city directoriesUlrich's Periodicals Directory, etc.). Shelf dummies are used in the reference stacks to direct users to the correct location. Some libraries also provide online ready reference resources via their Web pages. Selection decisions are usually made by the public services librarians who work at the reference desk, based on consensus developed over time. For online ready reference resources, try IPL2 or the Fugitive Fact File maintained by the Hennepin County Library.

reference collection

Books containing authoritative information not meant to be read cover to cover, such as dictionarieshandbooks, and encyclopedias, shelved together by call number in a special section of the library called the reference stacksReference books may not be checked out because they are needed by librarians to answer questions at the reference desk. Their location and circulation status is usually indicated by the symbol "R" or "Ref" preceding the call number in the catalog record and on the spine labelSee alsoready reference.

reference desk

When a person has a question about how to find specific information or how to use library services and resources, assistance can be obtained by contacting the public service point, usually located near the library's reference collection, in person, by telephone, or in some libraries via e-mail. A professionally trained reference librarian scheduled to work at the reference desk will provide an answer or refer the inquirer to a knowledgeable source. In large public and academic libraries, the reference desk may be staffed by two librarians, especially during periods of peak use. Compare with information deskSee alsodigital referencereference interview, and roving.

reference services

All the functions performed by a trained librarian employed in the reference section of a library to meet the information needs of patrons (in person, by telephone, or electronically), including but not limited to answering substantive questions, instructing users in the selection and use of appropriate tools and techniques for finding information, conducting searches on behalf of the patron, directing users to the location of library resources, assisting in the evaluation of information, referring patrons to resources outside the library when appropriate, keeping reference statistics, and participating in the development of the reference collection. For an online guide to reference services, see the tutorial ORE on the Web, courtesy of the Ohio Library Council. See alsocollaborative referencecooperative referencedigital referenceready reference, and Reference and User Services Association.

reference source

Any publication from which authoritative information can be obtained, including but not limited to reference books, catalog records, printed indexes and abstracting services, and bibliographic databases. Individuals and services outside the library that can be relied upon to provide authoritative information are considered resources for referral.

remote access

Communication with a geographically distant computer system or network as if one were a local user. To log on to a network server, the user may be required to enter an authorized username and/or password. Special communications software and/or hardware, such as a modem or dedicated line, may also be required. Wirelesscable modem, and DSL (Digital Subscriber Line) technologies provide alternative methods of accessing computer systems remotely. In most online library catalogs, a certain number of ports are reserved for remote access to accommodate off-site users. Compare with direct accessSee alsoauthentication.

restricted access

The privilege of using a library collection under specific conditions established as a matter of library policy. In archives and special collections, the use of rare books, manuscripts, and other unique and valuable materials may be limited to a particular room or a certain method or by appointment only. In the United States, large private university libraries may limit access to the stacks to registered students, faculty, and staff and to outside researchers granted special permission to use specific collections. The opposite of unrestricted. Compare with controlled accessSee alsoclosed stacks and open stacks.

Also refers to the policy of limiting access to an online resource or service to members of a particular community, such as the students, faculty, and staff of a university or the walk-in patrons of a public library. The most common method is for the vendor to check the network address of the user�s computer. Passwords or certificates may also be issued.

In public libraries, access to controversial or sensitive materials may be limited by placing them on a "restricted shelf" or in a locked case, usually to prevent children from using them without parental permission. The American Library Association has stated that such restrictions are a violation of the Library Bill of Rights; however, when restricted placement is adopted to protect library materials from theft or mutilation, or because of statutory authority or institutional mandate, such policies must be carefully formulated and administered to ensure they do not violate established principles of intellectual freedom.

revised edition

An edition in which a previously published work is substantially altered by correction, deletion, or the addition of supplementary material, either by the original author/editor or another writer, usually to expand the content or bring it up-to-date. Some revised editions are not as "revised" as they claim to be (caveat emptor). The extent of revision may be indicated in a new foreword or preface. Frequency of revision usually depends on the amount of new material available but may also be linkd to a decline in sales of the preceding edition. In library cataloging, the abbreviation Rev. ed. is given in the edition statement of the bibliographic record to indicate that an edition is revised. Usually synonymous with second edition. Compare with expanded edition.

RFID

An abbreviation of radio frequency identification. The use of microchips to tag library materials and the library card, enabling patrons to check out items by walking through a self-service station equipped with an antenna that emits low-frequency radio waves. When an RFID tag (transponder) passes through the electromagnetic zone, a reader (antenna + transceiver) decodes the data encoded in the tag's integrated circuit, passing it to a computer that automatically links data from the physical item(s) to the patron record corresponding to the library card. Line-of-sight is not required for this wireless non-contact system. In some libraries, RFID technology has replaced barcodes and optical technology in circulation systems. Tags are available in various shapes and sizes for use in a wide range of applications, with read/write capability for interactive applications. For more information on RFID in libraries, please see the January 2009 issue of Library Journal.

Because high-frequency radio waves can be used to track moving objects at a distance, the introduction of RFID technology in libraries has raised concerns about privacy. In January 2005, the Council of the American Library Association adopted a Resolution on Radio Frequency Identification (RFID) Technology and Privacy Principles to address issues of privacy and confidentialityClick here to learn more about RFID technology. See alsoself-checkout and skimming.

 

technical journal

journal devoted to a particular branch of engineering or technology, providing information for technicians in the field (exampleComputing in Science and Engineering). Articlepublished in technical journals are indexed in Applied Science and Technology IndexCompendexINSPEC, etc.

technical processing

All the activities and processes concerned with acquiring, organizing, preparing, and maintaining library collections, including cataloging and physical processing, usually accomplished "behind the scenes" by the technical services department of a library. When the department is understaffedarrears may accumulate. See alsocentralized processing.

technical report

A scientific paper or article describing research or other significant developments in a field of the applied sciences. When submitted to a military agency, such a report may be classified or subject to other restrictions on accessClick here to connect to the Virtual Technical Reports Center maintained by the University of Maryland Libraries. See alsoe-printNational Technical Information Servicepreprint, and Standard Technical Report Number.

technical services (TS)

Library operations concerned with the acquisition, organization (bibliographic control), physical processing, and maintenance of library collections, as opposed to the delivery of public servicesTechnical processing is performed "behind the scenes," usually in a technical services departmentSee alsoAssociation for Library Collections and Technical Services.

turnaway

In online systems, denial of access to an authenticated user when the allowable maximum number of simultaneous users is exceeded. Some database software includes an administrative feature designed to track and report turnaway statistics to the subscriber, for use in evaluating the need to upgrade the subscription.
 

union list

A complete list of the holdings of a group of libraries of materials (1) of a specific type, (2) on a certain subject, or (3) in a particular field, usually compiled for the purpose of resource sharing (exampleUnion List of Serials in the Libraries of the United States and Canada and its continuation New Serial Titlesissued by the Library of Congress). The entry for each bibliographic item includes a list of codes representing the libraries owning at least one copy. Union lists are usually printed, but some have been converted into online databases (see this example, courtesy of the Center for Research Libraries).
 

variant edition

An edition that includes changes made in the work by the author, sometimes ranging from first composition all the way to publication in a definitive edition, allowing the reader to see the evolution of the text. Compare with variorum edition.

virtual library

A "library without walls" in which the collections do not exist on papermicroform, or other tangible form at a physical location but are electronically accessible in digital format via computer networks. Such libraries exist only on a very limited scale, but in most traditional print-based libraries in the United States, catalogs and periodical indexes are available online, and some periodicals and reference works may be available in electronic full-text. Some libraries and library systems call themselves "virtual" because they offer online services (exampleColorado Virtual Library).

The term digital library is more appropriate because virtual (borrowed from "virtual reality") suggests that the experience of using such a library is not the same as the "real" thing when in fact the experience of reading or viewing a document on a computer screen may be qualitatively different from reading the same publication in print, but the information content is the same regardless of format.

virtual tour

An online tour of a library's facilities, usually available over the Internet (click here and here to see examples). Formats vary but some include clickable floor planlinked to photographs with accompanying text describing the collections and services available at each location. To see other examples, try a search on the keywords "virtual tour and library" in Google Images.

virtual union catalog

An automated system for searching the holdings of two or more discrete library catalogs together, using Z39.50 and/or other mechanisms for broadcast search and retrieval, in contrast to a centralized union catalog in which catalog records are gathered in a single database or physical location.
