OCLC MARC Format Changes
On June 1, OCLC implemented changes related to the OCLC MARC Format Update 2008 in the Connexion browser and client. These changes are based on MARC 21 Bibliographic, Authority and Holdings Formats, Updates No. 7 (dated October 2006), MARC Code List changes and additions, and a few changes suggested by users and OCLC staff.
Changes include, but are not limited to:
- New bibliographic indexes: Language of Cataloging Description (040 $b) and Access Restrictions (506 $a and $f)
- 024 subfield $z (Cancelled/invalid standard number or code) added to Standard Number indexes (sn: and sn=)
- Addition of $j (Relator term) in 111, 611, 711 and 811
- Addition of field 506 (Restrictions on Access Note) in Holdings records
- Addition of codes from the IAML list of musical composition codes in 047
- New authority index: Cartographic Data index (034 $d, $e, $f, $g and $z)
The ability to search codes from the International Association of Music Libraries, Archives and Documentation Centres (IAML) list of musical composition codes in 047 $a in both Connexion browser and client will be available later in 2008.
All new searching and indexing capabilities can be used in both Connexion interfaces (browser and client). In Connexion client, new indexes will not appear in drop-down lists, but can be input manually via the command line. Client drop-down lists will be updated with new indexes in the next version of the client.
For complete details, see OCLC Technical Bulletin 255.
