014 Linkage number (R) (Variable Data Fields)
Field Definition and Scope:
This field contains a system control number transferred from field 001 (Control Number) or field 004 (Control Number for Related Bibliographic Record) in a separate holdings record distributed by a bibliographic network when the receiving organization places its own holdings record control number in field 001 or its own related bibliographic record control number in field 004. The originating network is identified in subfield $b (Source of number).
Guidelines for Applying Content Designators:
Indicators:
First Indicator - Type of linkage number:
The first indicator position contains a value that indicates whether the control number contained in subfield $a (Linkage number) or $z (Cancelled/invalid linkage number) is for a holdings record or for a related USMARC bibliographic record.
Second Indicator - Undefined:
The second indicator position is undefined and contains a blank (#).
Subfield Codes:
$z Cancelled/invalid linkage number
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 cancelled or invalid linkage numbers related to a valid number.
Embedded Holdings Information:
When holdings information is embedded in a related USMARC bibliographic record, no field 014 is input.
Related USMARC Field or Document:
004 Control Number for Related Bibliographic Record
