Relationship between Bibliographic 008/39 and field 040 subfield $a NLC

A validation check has been created to generate an error message if a cataloging user changes 008/39 (Cataloging source) to a value other than blank when field 040 (Cataloging Source) subfield $a (Original cataloging agency) contains the symbol NLC. A similar check already exists for the symbol DLC.
