What does the subfield $F indicate in a MARC record?

The subfield $F in a MARC (Machine-Readable Cataloging) record is used to indicate the date associated with the work being cataloged. In bibliographic records, the date can refer to various aspects, such as the date of publication or the date of creation of the work. This detail is crucial for accurately recording and retrieving information about publications, as it helps users identify the specific version or edition being referenced, especially when multiple editions exist over time.

In the context of MARC records, the systematic arrangement of data fields and subfields allows librarians and media specialists to efficiently manage and share bibliographic information, ensuring that users can find materials based on specific criteria, including the date.
