Local data. Fields 901–907 are not part of the standard MARC format. Define these fields to fit your needs. 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 901–907 do not remain in the master record. They are retained in archive records, institution records, exported records, and OCLC-MARC records.
