Authority Control

Authority Control Jobs

 

The WRLC Network Zone runs three different jobs in Alma for authority control every day. These jobs apply only to Network Zone-linked bibliographic records that have been added or updated since the last time the job was run, also to bibliographic records with subject headings linked to authority records that have been updated since the last job was run.

 

More information can be found in the Alma Knowledge Center.

Ex Libris runs a re-indexing job on all repository records twice a year (from November to January, and from May to July). This process applies both authority control jobs to all records in the repository; this is the only time that the jobs will run on old records as well as new ones.

The WRLC did not have authority control jobs running in the Network Zone until 2022. In the Fall of 2021, the WRLC Metadata Committee reviewed authority control in Alma and came to the conclusion that, although the jobs are not perfect, the benefits outweigh the drawbacks. A detailed description of this review can be viewed in the Authority Control Testing Fall 2021 document created by the WRLC Authority Control Subgroup. The official WRLC Policy on Authority Control can be found in the WRLC Network Zone Bibliographic Record Policies document.

Authority Control Rules

 

In addition, WRLC created several Authority Control rules to mitigate some of the mistakes commonly committed by the Link BIB Heading and Preferred Term Correction jobs.

The jobs and rules mentioned above are configured in the Network Zone, and therefore only apply to records linked to the Network Zone. Below are are the current configurations in the WRLC Network Zone for authority control.

Undifferentiated non-preferred personal name : Prevents preferred term correction for personal names in an X00 field to be linked to an authority record with an undifferentiated non-preferred personal name
