the purpose of bibliographic control is to: identify, select, and obtain an item by searching the record using the access points (author, title, subject). The results show what the library owns, its scope and currency.

the main fields used to provide access in a record are (1) author, (2) title, (3) subject, cross references, and classed subject, (4) format entry, (5) language entry, and (6) notes.

a collection of bibliographic records in MARC format, maintained on a computer terminal with continuous Internet access. The software used to run the OPAC is not owned by libraries, but does provide standard search and retrieval functions by name, title, subject, genre. The public is provided free access in any public, academic library through a GUI in the library or on the library web page. OPACs also perform other library functions such as administration, acquisition, cataloging, circulation.

the process of creating entries for a catalog and preparing an item for the shelf. The 5-step process is:
(1) bibliographic description analysis
(2) subject analysis
(3) assign classification notation
(4) assign authority control terms
(5) MARC tags

all the elements of data needed to identify an item contained in a bibliographic record. In library cataloging, each edition of an item is represented by its own record and accessed by the same author, same title and same subject. In AACR2R, the 8 areas of description are identified:
(1) title and person of responsibility
(2) edition
(3) material specific details
(4) publication, copyright, imprint
(5) physical description
(6) series
(7) notes
(8) standard #, terms of availability (ISBN, ISSN, price)

examination of the item to assign most appropriate subject headings that describe its content and provide access points in the bibliographic record for retrieval in the catalog, database or index.

the process of dividing objects or concepts into hierarchical classes, subclasses, and sub-subclasses based on the content that distinguish the item.

the procedure of identifying a heading (name, uniform title, title series, subject) in an authorized list to preserve consistency of form in bibliographic records. The first heading to use is a standardized name.

MAchine Readable Cataloging is an international standard digital format created by LC in the 1960s to promote the sharing of bibliographic records with libraries. Resource sharing, library automated systems, and reliable data are some of the benefits of computerized cataloging.
MARC has three components: (1) Record structure (Z39.2), (3) Content designation (codes and conventions), and (3) Data content (AACR2R, LCSH).

A MARC record is divided into fields which contain elements of bibliographic description. Each field is assigned a three-digit code that describes the content it holds. Tags are organized in hundreds indicating a group of tags with XX, for the range 00-99

0XX fields - Control information, numbers, codes
1XX fields - Main entry
2XX fields - Titles, edition, imprint
3XX fields - Physical description, etc.
4XX fields - Series statements (as shown in item)
5XX fields - Notes
6XX fields - Subject added entries
7XX fields - Added entries other than subject or series
8XX fields - Series added entries (other authoritative forms)
