Standard number or code published on an item which cannot be accommodated in another field (e.g., field 020 (International Standard Book Number), 022 (International Standard Serial Number), 027 (Standard Technical Report Number)). The type of standard number or code is identified in the first indicator position or in subfield $2 (Source of number or code).
Number or code is copied from subfield $a of field 024 (Other Standard Identifier) of the MARC bibliographic record that represents the description of the item for which a separate holdings record is created. May also contain any additional codes or a canceled/invalid code from subfields $d or $z of field 024 in the bibliographic record.
Additional information and description of the use of field 024 (Other Standard Identifier) is in the MARC 21 Format for Bibliographic Data.
