Responsible Parties Rule:

The MARC 21 Format for Authority Data serves as a vehicle for authority data of all types from any organization. In general, the responsibility for the data content, content designation , and transcription of authority data within a MARC record may be determined by examination of the field indicated in the Responsible Parties section below. The data content of certain data elements, however, is restricted when the element is an agency-assigned or a controlled-list data element.

Responsible Parties:

In unmodified records, the organization identified as the original cataloging source in 008/39 (Cataloging source) and/or subfield $a (Original cataloging agency) of field 040 (Cataloging Source) is responsible for the content of the record. The organization identified as the transcribing agency in subfield $c (Transcribing agency) of field 040 is responsible for the content designation and transcription of the data.

In modified records, the organizations identified in subfields $a (Original cataloging agency) and $d (Modifying agency) of field 040 (Cataloging Source) are collectively responsible for the content of the record. Organizations identified as transcribing or modifying agencies in subfields $c and $d of field 040 are collectively responsible for the content designation and transcription of the data.
