About Library Hub Cataloguing

The Library Hub Cataloguing service is provided by OCLC on behalf of Jisc, on the OCLC CBS platform. The Web interface can be accessed at: https://cataloguing.libraryhub.jisc.ac.uk/

Please see below for more information about the service and Terms of Use.

The Library Hub Cataloguing service allows eligible libraries to search and download MARC records for use in their local catalogue. This service is available through a web interface and Z39.50 connection, both of which require authentication. Access is available to current Library Hub contributors and Jisc members.

You will find details of the Z39.50 search in the Cataloging FAQ.

Creating the Cataloguing database

The data in the Library Hub Cataloguing database is deduplicated. One of the records in a set of duplicates is used as the 'base record' and fields from the other records in the set are added to that base record to create the final consolidated record. The processes involved in choosing the base record and creating a consolidated record will be documented and discussed as the service develops.

Where a record has OCLC provenance, as indicated by the presence of an OCLC 994, the record will not be used as the base record to create a consolidation unless all the records in a set of duplicate records have OCLC provenance. Where this occurs, OCLC have imposed a restriction on the fields that can be included in the consolidated record, known as mini-MARC. Similarly a single, unconsolidated, record that has OCLC provenance will also be given in mini-MARC form.


The fields that may be included in an OCLC mini-MARC record are detailed below.

Note: The 'mini-MARC' relates to the Cataloguing database only. In the Discover and Compare services non-MARC data formats are used, so in the database that underpins Discover and Compare the supplied records are used in their entirity.
