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.

A large, regularly updated file 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) software. Content 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 (EBSCO, OCLC, 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.

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 (book, article, dissertation, report, musical composition, etc.) produced by a particular author, editor, composer, 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 cite

A brief, objective representation of the essential content of a book, article, speech, report, dissertation, patent, standard, 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 informative, indicative, critical, 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

Enduring works of poetry or prose that express ideas and emotions of universal human interest in a form and style embodying excellence.

Any one of the topics or themes of a work, stated explicitly in the text or title or implicit in its message. In library cataloging, a book or other item is assigned one or more subject headings as access points, to assist users in locating its content by subject. In abstracting and indexing services, the headings assigned to represent the content of a document are called descriptors. Abbreviated subj. See also: aboutness and subject analysis.
