Authority records

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 or a 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 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.
