Catalogers are not required to maintain identifiers coded in the 024 field of PFAN authority records. When an 024 field is present in an authority record that is being reported for deletion (for example, in the case of a duplicate), catalogers should transfer the field to the record that is to be retained. When two authority records are being collapsed into one, and each record has a different 024 field, catalogers should include both 024 fields in the updated record. | Catalogers are not required to maintain identifiers coded in the 024 field of PFAN authority records.
