Local processing data. Fields 945–949 are not part of the standard MARC format. Define these fields to fit your needs for local processing information. Before incorporating any of these local fields into your cataloging routine, contact your local system vendor. Indiscriminate or inconsistent use of these fields may adversely affect the consolidation of records and local data in the creation of a local system database.
Fields 945–949 do not remain in the master record. They are retained in archive records, exported records and OCLC-MARC records.
