MARC 21 Concise Bibliographic: Classification and Call Number Fields (05X-08X)

Fields 050-088 fields contain classification and call numbers related to the item described in the bibliographic record. Identification of the character sets used in encoding the bibliographic data is also provided for by a field in this group.

050 - LIBRARY OF CONGRESS CALL NUMBER (R)

A classification or call number that is taken from Library of Congress Classification or LC Classification Additions and Changes. The brackets that customarily surround alternate class/call numbers are not carried in the MARC record; they may be generated based on the presence of repeated $a subfields.

A value that indicates whether the item is in the LC collections.
- # - No information provided
  A call number assigned by an organization other than LC.
- 0 - Item is in LC
  May be used by organizations transcribing from LC copy on which the call number is neither enclosed within brackets nor preceded by a Maltese cross.
- 1 - Item is not in LC
  May be used by organizations transcribing from LC copy on which the call number is enclosed within brackets or is preceded by a Maltese cross. The brackets that customarily surround call numbers for items not in LC are not carried in the MARC record; they may be generated.
Second - Source of call number
A value that indicates whether the call number has been assigned by the Library of Congress or another organization.
- 0 - Assigned by LC
  May be used by organizations transcribing from LC copy.
- 4 - Assigned by agency other than LC
  A record may contain only one of these fields with value 4 in the second indicator position.

Subfield Codes

$a - Classification number (R)
(The classification number is an authoritative-agency data element.)

$b - Item number (NR)
Organizations that use the Cutter-Sanborn Three-Figure Author Table may conform to LC item number practice by applying Subject Cataloging Manual: Shelflisting procedures.
