Knowledge base collection data is dynamic. As OCLC refreshes data in the global knowledge base, your links and holdings in WorldCat stay up-to-date. Records are output on an ongoing basis and will reflect title additions and deletions as well as updates to your library-specific links. Note: An OCLC Cataloging Subscription is required to enable holdings in WorldCat.
There are multiple methods to add collections to your local knowledge base and most libraries use a variety of options. Knowledge base collections in Collection Manager should reflect your library's subscriptions. For some collections, you will be able to select a global knowledge base collection as a whole and for other collections, you will need to select a subset of titles to match your subscription. OCLC partners with some providers who, at your request, will send OCLC your library-specific holdings so that we can load your collection data for you. See Providers and contacts for automatic collection loading to see if your provider participates in automatic collection loading.
Once you add one or more knowledge base collections in Collection Manager, you can expose collection data to other applications and services.
