Definition

Local data. Fields 901-907 are not part of the standard MARC 21 format. You may define these fields to meet your needs. Before incorporating any of these local fields into your cataloging workflow, contact your local system vendor. Indiscriminate or inconsistent use of these fields may adversely affect the consolidation of records and local data needed in the creation of a local system database.

With the exception of subfield ǂ6, the numeric subfields may be locally defined or used in accord with their control subfield definitions.

Fields 901-907 do not remain in the master record. They are retained in exported records and records delivered via other services.

Field 910 and fields 945-949 may also be used for local data.
