Authority records

Find out how an authority record is defined.

You can search the authority file to determine if an authoritative heading exists. If an authorized heading exists, it is described in an authority record.

An authority record contains information about a name, a uniform title, or a topical subject heading. Each authority record may contain the established form of the heading, see from references, see also from references, and notes. The record also contains coded data that describes the characteristics of the heading or record.

Records have fixed-length fields that contain coded information from the MARC 21 Leader, 005, and 008 fields. Records have variable-length fields that contain coded and textual information.
