NOTE:  See MARC 21 Format for Bibliographic Data (016 National Bibliographic Agency Control Number) for code definitions not given below.


Field 016 contains unique numbers assigned to records by national bibliographic agencies other than the Library of Congress.  The control number may also appear in field 001 (Control number) in records distributed by the national agency.  This number is the record control number used in a national bibliographic agency system, rather than a number used for entry in a national bibliography (cf. field 015 National Bibliography Number).  Field 016 is generally added during batchload rather than being input directly by the national agency.

In CONSER records, field 016 is used for primarily Library and Archives Canada and National Library of Medicine record control numbers.  The LAC control number also appears in subfield $a of field 010 in LCCN format.  If an LC control number is input in subfield $a, the LAC bibliographic control number is moved to subfield $z of field 010.

Following are examples of LAC bibliographic control numbers as they appear in field 016 and field 010.
