Holdings are used by libraries to communicate what they currently own or license by associating their unique institution symbol with specific records in WorldCat. Libraries set and maintain their holdings information by using tools and services included in OCLC cataloging subscriptions.
WorldCat holdings information represents the collective inventory of OCLC member libraries. As your library collections evolve, it is extremely important to maintain accurate holdings as this information informs a number of features and capabilities found in other OCLC subscriptions, including FirstSearch/WorldCat Discovery, WorldShare Interlibrary Loan, OCLC Cataloging and Metadata and more.
When a library’s holdings are indicated in WorldCat, that library can take advantage of tools that increase efficiency and save time.
Your OCLC Cataloging and Metadata Subscription includes all the tools you need to set and maintain your WorldCat holdings via a number of approaches depending on your needs.
Note: WorldShare Collection Manager is included in your OCLC Cataloging and Metadata Subscription. To request access go to oc.lc/getcm

You can use WorldCat holdings audience levels to further manage your holdings. Audience levels allow you to control who can see specific titles or copies of an item in your collection. By assigning a specific level to a holding, you can suppress the holding from the general public.
Note: Your institution must be a WorldShare Management Services (WMS) library to use this feature.
You must maintain accurate metadata once you have set your holdings in WorldCat. The OCLC number and ISBN or ISSN must be added to each bibliographic record in your local OPAC in order for deep links to function accurately.
You can add the OCLC number and ISBN or ISSN to a bibliographic manually or receive bibliographic records from OCLC and overlay them with the existing bibliographic records in your local OPAC.
