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).
See also field 010 (Library of Congress Control Number), field 016 (National
Bibliographic Agency Control Number), and field 035 (System Control Number) for control
numbers for related bibliographic records assigned by other sources.

INPUT CONVENTIONS
Punctuation - Field 014 does not end with a period.
Repeatability - Each type of linkage number is recorded in a separate field 014. Subfield $z
is repeatable for recording multiple canceled or invalid linkage numbers related to a
valid number.
Embedded Holdings Information - When holdings information is embedded in a related MARC bibliographic record, no field
014 is input.
