Export specifications

Cataloging export converts bibliographic and authority records to the OCLC-MARC format. It writes that record to a file or directs it to a communications port.

Export characteristics: Bibliographic records 

Exported bibliographic records have the same format and character set as OCLC- MARC records output to FTP.

The following applies to exported bibliographic records:

  • Maximum size = 6,144 characters
  • In the 003 field, records contain OCLC’s organization symbol: OCoLC
  • The 005 field contains the date and time the export was executed
  • Byte 22 of the leader may contain an export transaction code. Transaction codes were stored in byte 22 prior to November 12, 2006. Records exported before that date, byte 22 may contain one of the following values:
    • b/ for exported via Connexion
    • e for exported via Cataloging service or OCLC Selection
    • x for exported via OCLC Connexion client

 Note: Since November 12, 2006, all transaction codes are stored in field 994. For historical details and a complete list of transaction codes, see the information on field 994 in Content Designators for Bibliographic Data.

The following table details what is and is not included in exported bibliographic records.
