-
- bibliographic record
- Contains the cataloging information that describes the physical format and intellectual content of a single entity (a book, video, computer file, CD, etc.). Catalogers create records by encoding this information using tags, indicators, and subfield codes in a standard format called MARC 21 ( MAchine- Readable Cataloging). Each record is divided into fields (author, title, subjects, etc.) Fields are subdivided into subfields (place of publication, publisher, etc.).
-
- BKS
- See Books format.
-
- Book number
- The part of a call number that distinguishes a specific item from other items within the same class number, also called a Cutter number. A book number is composed of letters from the author's name or letters from the title main entry and numbers. There are several systems for creating book numbers.
- A library using the Cutter-Sanborn system can have D548d indicate David Copperfield by Dickens (where D stands for the D of Dickens, 548 stands for "ickens" and d stands for David Copperfield). See also call number; Cutter number; work mark.

Several versions of MARC are in use internationally, the most predominant of which is MARC 21, created in 1999 as a result of the harmonization of U.S. and Canadian MARC formats. UKMARC is used primarily in the United Kingdom. UNIMARC is widely used in Europe. Besides formats for bibliographic records, the MARC 21 family of standards now also includes formats for authority records, holdings records, classification schedules, and community information.
