What is a discontinued knowledge base collection?

When a WorldCat knowledge base collection has been labeled discontinued, the collection is no longer being updated by provider data. Discontinued collections should be deselected, as OCLC cannot ensure the accuracy of the title data.

Often a collection is discontinued because a new version of the collection available from the provider. We recommend you select the new equivalent collection if you still have access to those title.

If there is no equivalent collection available and the collection is discontinued, we recommend that you download the KBART data for that collection, create a collection, and upload the KBART data to the collection so that you have your own version of the needed collection.

For more information, see Discontinued knowledge base collections.
