How do I synchronize holdings between Alma and WorldCat?

Applies to
  • WorldShare Collection Manager

OCLC provides two different types of WorldShare Data Sync collections that Alma users can utilize to update their holdings in WorldCat. 

  1. To synchronize bibliographic title-level WorldCat holdings at the OCLC institution symbol level by sending full MARC bibliographic records, create a Bibliographic Data sync Collection in WorldShare Collection Manager. This is the type of data sync collection most libraries use.
  2. To synchronize local holdings with OCLC  by sending MARC Format for Holdings Data (MFHD) records, create a Local Holdings Record Data sync Collection in WorldShare Collection Manager. This type of collection will update copy-specific information, such as call numbers, holdings locations, and detailed holdings.

Note:  If the purpose of your collection is to set/delete holdings in WorldCat for every matching record found, you should create a bibliographic data sync collection.

Use the Test FTP feature in Alma

Almost immediately after a file upload completes, the OCLC file exchange system moves the file into a queue for subsequent processing and it is no longer available on the OCLC file exchange server.

When you click the Test FTP button in Alma, you will receive a message indicating "Ftp upload success" if the Alma settings are configured correctly to work with your OCLC file exchange account.

You may also receive a message from Alma indicating "Ftp delete fail" or "Ftp download fail".  You may disregard these failure messages, as Alma attempts to delete the test file immediately after upload but it is likely no longer available in the upload directory to be deleted.

The "Ftp upload success" message from Alma confirms that the SFTP connection to your OCLC file exchange account was successful.
