040 Record Source (NR) (Variable Data Field)

Field definition and scope:

Field 040 contains the USMARC code or the name of the organization(s) that created the original record, assigned USMARC content designation and transcribed the record into USMARC, or modified an existing USMARC record. The USMARC codes in field 040 specify the responsible parties for the content, content designation, and transcription of a classification data record. The source of this code is USMARC Code List for Organizations that is maintained by the Library of Congress. 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.
