Announcement: NACO MARC21 046: Subfields $q and $r available for use

MARC field 046 subfields $q (establishment date) and $r (termination date) are now valid for use in NACO corporate name authority records. Existing NACO corporate body records that have establishment date and termination date in subfields $s and $t will not be programmatically updated to use subfields $q and $r. However, when updating an already existing corporate body record, NACO catalogers are encouraged to evaluate the 046 field and manually update the subfields to $q and $r as needed.

Note: Subfield $s (start period) and subfield $t (end period) are also valid for use in NACO corporate name authority records in some cases. If subfield $s and subfield $t do not represent establishment date and termination date, do not change the subfield values.

NACO documentation will be updated soon to reflect the change in practice.
