NAME: Adding Subfield $5 to Field 580 in the MARC 21 Bibliographic Format

SOURCE: OCLC, in consultation with Rare Books and Manuscripts Section (RBMS)

SUMMARY: This paper presents a case for adding subfield $5 (Institution to which field applies) to field 580 (Linking Entry Complexity Note) in the MARC 21 Bibliographic Format.

KEYWORDS: Field 580 (BD); Linking Entry Complexity Note (BD); Subfield $5, in field 580 (BD); Institution to which field applies (BD)

RELATED: 2024-04; 2023-DP08

12/14/23 – Made available to the MARC community for discussion.

01/24/24 – Results of MARC Advisory Committee discussion: Most MAC members endorsed fast-tracking the discussion paper considering its connection to Proposal 2024-04. Two requests were made for the inclusion of examples showcasing the utilization of subfield $8 and a scenario involving a title change in a library's local bound volume. In a straw poll, the committee voted in favor of processing the paper as a Fast-Track proposal. The paper was referred to the MARC Steering Group for final processing and approval as a Fast-Track proposal.

Discussion Paper No. 2024-DP01: Adding Subfield $5 to Field 580


While writing our proposal for adding $5 (Institution to which field applies) to some linking entry fields (Proposal No. 2024-04), we realized that this subfield should also be added to field 580 (Linking Entry Complexity Note) because field 580 provides a description of relationships recorded in linking entry fields 760-787. If the relationship recorded in the linking entry field was specific to an institution, then the note explaining that relationship would also be specific to that institution.


A linking entry field may have the relationship between resources explained four ways: 1) with an indicator used to generate a display constant (e.g., Issued with:), 2) with a relationship code recorded in $4; 3) with a relationship designator recorded in $i; or 4) with field 580. This is an example from the current MARC 21 page for field 580 of a 580 field used with a linking entry field:

580 ##$a Cumulates: Deutsche Bibliographie. Wöchentliches Verzeichnis.
787 1#$t Deutsche Bibliographie. Wöchentliches Verzeichnis

As the current field definition and scope state, field 580 may also be used to state a relationship when there are no corresponding linking entry fields. An example given for using field 580 without a linking entry field is "a serial bearing a relationship to one or more publications which cannot be named."

The subfield $5 would be used in field 580 most often when describing a published resource that is part of an archival collection. The collection itself is unique, but the published resource is not, so the subfield $5 is needed to indicate that the relationship is only for an institution's copy of the resource.

We believe that the only reason that subfield $5 has not been already added to this field is that there was no need to when the linking entry fields did not have $5. Many 5XX fields have subfield $5 including 500 (General Note), 501 (With Note), and 563 (Binding Information).

The future of this discussion paper is linked to that of our proposal (2024-04). If that proposal is approved, supporting this discussion paper logically follows.


In field 580 (Linking Entry Complexity Note) of the MARC 21 Bibliographic Format, add new $5 as follows:

$5 - Institution to which field applies (NR)
See description of this subfield in Appendix A: Control Subfields.


Note: In these examples, we have included $5 in the linking field in square brackets because this is not valid in the MARC format but would be if our related proposal is approved.

The MARC to BIBFRAME specifications for the 580 field indicate that this is a note in bf:Work. When adding a subfield $5 to the field to indicate that the note is copy-specific, it should go to bf:Item. The BIBFRAME data conversion programs would need to accommodate the addition of $5 to this MARC field if this were to be approved.


6.1. Do you agree that there is a use for subfield $5 in field 580?

6.2. Are additional examples needed?

6.3. Are there any potential consequences to this proposed change that have not been considered?

6.4. Would MAC consider turning this into a fast-track proposal to be discussed in conjunction with the linking entry $5 proposal for fields 773, 774, and 787?
