OCLC Parallel Records are available
Connexion is OCLC’s flagship cataloging service and available as a Cataloguing Client and a Browser.
Standards for Cataloguing are available on the OCLC website,
It is possible with OCLC Connexion Browser and Connexion client to create the full range of cataloguing encoding levels for bibliographic records. OCLC specifies a minimum level of AACR2 for the OCLC-MARC encoding levels
Records that meet the requirements of second-level description (AACR2, rule 1.0D2).
- Core-level cataloging. Records that meet the requirements of first-level description (AACR2, rule 1.0D1) and some of the requirements of second-level description (AACR2, rule 1.0D2).
- Minimal-level cataloging. Records that meet the requirements of first-level description (AACR2, rule 1.0D1).
- Abbreviated-level cataloging. Brief records that do not meet the requirements of Minimal-level cataloging specifications ( ELvl code 3).
- Dublin Core. All records created in Dublin Core ( ELvl code 3).
The full range of OCLC-MARC encoding level differ slightly to LCMARC encoding level.
The Recommendations for Cataloguing Standards on the New Zealand National Union Catalogue can be used for the Mimimal-Level cataloging and when creating Abbreviated-Level cataloging when creating records on OCLC's Connexion cataloguing service.
CatExpress is a copy cataloguing client and cannot be used to create and edit bibliographic records. It can be used to add local data and holdings and copy a record to a library catalogue. http://www.oclc.org/catexpress/about/default.htm
