MARC 024 Other Standard Identifier (Authority)

Revision as of 14:22, 1 April 2015 by DeborahLeslie (talk | contribs)

MARC field 024 in the Authority format contains a standard number or code associated with the entity named in the 1XX field which cannot be accommodated in another field (for example, field 020 (International Standard Book Number)). This field is repeatable.

Commonly-used tags


1st: 7 - Source specified in subfield ǂ2
2nd: Undefined

Subfield delimiters

ǂa Standard number or code (NR)
ǂz Canceled/invalid standard number or code (R)
ǂ2 Source of number or code (NR)

Policy and formulation

Record the VIAF ID for personal and corporate names. If the same entity is or might be spread over separable headings, record each ID number in a separate 024
