016 National Bibliographic Agency Control Number (R) (Variable Data Field)
Field 016 contains unique numbers that have been assigned to a record by a national bibliographic agency other than the Library of Congress. (Library of Congress control numbers are recorded in field 010 .) The control number may also appear in field 001 (Control Number) in records distributed by the same national agency. An organization using the record may remove the national bibliographic agency control number from field 001 and use field 001 for its own system control number. 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) .
A record may contain field 016 with a canceled or invalid control number of a previously-distributed record. A record may be canceled because it is a duplicate record for the same item.
The National level record requirement for this field is Mandatory if applicable.
