Definition |
Control number, assigned by a bibliographic network, of a separate holdings record or the related bibliographic record for which a separate holdings record is made. In separate holdings records distributed by a network, the holdings record control number is carried in field 001 and the control number of the related bibliographic record is carried in field 004. An organization receiving the holdings record may transfer the control numbers from fields 001 and 004 to field 014 and place its own holdings record number and related bibliographic record control number in fields 001 and 004. Fields 001 and 004 are displayed in Record Manager LHRs. In Connexion LHRs, field 001 is not displayed and field 004 is displayed as OCLC. The originating network is identified in subfield ǂb. |
