MARC 21 Format for Holdings Data: 016: National Bibliographic Agency Control Number (Network Development and MARC Standards Office, Library of Congress)

Control number, assigned by a national bibliographic agency other than the Library of Congress, of the related bibliographic record for which a separate holdings record is made.

This number is a record control number used in a national bibliographic agency system, rather than a number used for an entry in a national bibliography, field 015 (National Bibliography Number) of the MARC 21 Format for Bibliographic Data.

In separate holdings records distributed by the agency, the control number for the related bibliographic record is carried in field 004 (Control Number for Related Bibliographic Record). An organization receiving a holdings record may transfer the control number for the related bibliographic record from field 004 to field 016 and place its own related bibliographic record control number in field 004.

See also field 010 (Library of Congress Control Number), field 014 (Linkage Number), and field 035 (System Control Number) for control numbers for related bibliographic records assigned by other sources. See field 016 (National Bibliographic Agency Control Number) in the MARC 21 Format for Bibliographic Data for a detailed description of the structure of the Library and Archives Canada control number for bibliographic records.
