Definition

Local data. Formerly defined as User-Option Data, field 910 is not part of the standard MARC 21 format. You may use this field to meet your local needs. Before incorporating any local field into your cataloging workflow, contact your local system vendor. Indiscriminate or inconsistent use of a local field may adversely affect the consolidation of records and local data needed in the creation of a local system database.

Field 910 does not remain in the master record. It is retained in exported records and records delivered via other services.

Fields 901-907 and 945-949 may also be used for local data. They are repeatable and include the ability to define subfields as needed.
