FIELD DEFINITION AND SCOPE
Contains the control number assigned by the organization creating, using, or
distributing the record. For interchange purposes, documentation of the structure of the
control number and input conventions should be provided to exchange partners by the
organization initiating the interchange. The MARC code identifying whose system control
number is present in field 001 is contained in field 003 (Control Number Identifier). An
organization receiving a record may move the incoming control number from field 001 (and
the control number identifier from field 003) to field 035 (System Control Number), 010
(Library of Congress Control Number), or 016 (National Bibliographic Agency Control
Number), as appropriate, and place its own system control number in field 001 (and its
control number identifier in field 003).
