WorldShare Record Manager Release Notes, August 1, 2023


Release Date: 1 August 2023


This release of WorldShare Record Manager provides a new feature for participants in the OCLC Member Merge Program to merge two duplicate WorldCat records.

  • Builds upon the existing Record Manager 'Compare' feature to allow you to look at two WorldCat records side-by-side, field-by-field.
    • The visual field-by-field comparison allows you to easily identify gaps or differences in the WorldCat records.
    • A new merge dropdown list makes it easy for you to quickly merge the records directly from the Compare screen.
  • For existing users of WorldShare applications, this allows you to stay in your familiar interfaces without the need to go to Connexion client.

About the OCLC Member Merge Program


The OCLC Member Merge Program is designed to empower OCLC Members to reduce the presence of duplicate bibliographic records in WorldCat. Training and upgraded cataloging permissions enable Member Merge participants to merge existing duplicate WorldCat records. 


New participants receive documentation and training resources to review.  Once you complete the documentation and training and are ready a start a trial phase, an assigned OCLC reviewer will work with you to establish the process and provide sets of potential duplicate records to process. The review phase typically takes several months at a minimum depending on the volume and timing of the review sets submitted to the reviewer.  After you successfully complete the review process, you are granted full merging rights in WorldCat.
