040 Record Source

Field definition and scope:

Field 040 contains the MARC code or the name of the organization(s) that created the original classification record, assigned MARC content designation and transcribed the record into machine-readable form, or modified an existing MARC record. See Appendix F for a listing of organization code sources used in MARC 21 records.

The MARC codes in field 040 specify the responsible parties for the content, content designation, and transcription of a classification data record. If a library chooses to create a record for a classification number which has not been authorized by the particular classification scheme (such as one for a synthesized number), the classification scheme upon which it is based is specified in field 084 (Classification Scheme and Edition), and the library creating the record is identified in field 040.

Field 040 is NOT repeatable.
