Authority record variable fields

Discover the elements of the authority record variable fields.

Each authority record contains alphanumeric data. Tags are in sequence according to the first digit. However, they are not necessarily in numeric sequence within a block of tags beginning with the same number. Even though the nature of cataloging data is such that many tags are not repeated, most variable tags may be repeated.

Each variable field ends with a field terminator. The last field ends with both a field terminator and a record terminator.

In OCLC-MARC Records, any element, value, field, subfield, etc., marked obsolete is no longer valid. Current records will not contain these invalid codes. However, previously exported records may contain obsolete MARC coding.

 Note: See Authorities: Format and Indexes for additional information.
