FIELD DEFINITION AND SCOPE
 

Control number, assigned by a bibliographic network, of a separate holdings record or its 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 (Control Number) and the control number of the related bibliographic record is carried in field 004 (Control Number for Related Bibliographic Record). 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. The originating network is identified in subfield ‡b (Source of number).
