Update local holdings records efficiently

You can add or update your OCLC local holdings records (LHRs) in WorldCat through batch processing.

How it works

You may submit batch files on a regular schedule of your choice, or you may update with a one-time batch project and then maintain your LHRs online through the Connexion browser.

For more information, see the general guidelines. For details about record requirements, procedures for initiating projects, and procedures for submitting files, see the specifications or documentation.
