FIELD DEFINITION AND SCOPE

MARC code or 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 21 record. See Organization Code Sources for a listing of sources used in MARC 21 records.

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.

$d - Modifying agency
MARC code or the name of the organization responsible for modifying a MARC record. A modification is defined as any correction to a record, including data, content designation, or keying changes.

Subfield $d is not repeated when the same MARC code or name would occur in adjacent $d subfields. If the transcribing agency also modifies the record in the process of transcribing it, the MARC code or agency name is also recorded in subfield $d.
$6 - Linkage
See the description of this subfield in Appendix A: Control Subfields.
$8 - Field link and sequence number
