Please contact the provider/vendor from whom you purchased the subscription or individual titles. They should be able to tell you which OCLC knowledge base collection corresponds with the content you've purchased. The name the provider gives their collection does not always match OCLC's collection name, but the provider should be able to give you the corresponding OCLC collection ID.
Alternatively, if you've purchased a few titles, you can search for the titles in Collection Manager and see if they appear in a common collection from your provider.
Select the full collection if you have purchased access to all the titles within the collection. Otherwise, select only the titles you've purchased. See the Additional Information section below for more.
