Automated holdings updates for your Ebook Central owned and DDA-discoverable holdings are now available for Alma. 
To enable this service: If you are a member of a consortium on Ebook Central, we will send the consortium owned and DDA titles that are visible to your patrons on your Ebook Central site along with your locally-held titles.

Ebook Central also offers automated holdings management with Ex Libris' Intota and OCLC's WorldCat Knowledgebase. For more information, access the following support articles:
