Does the service set holdings for a library’s entire collection?
The service sets holdings against ISSN-based resources for which we have a record in WorldCat. We don’t set holdings for non-ISSN based resources in WorldCat. We’re dedicated to setting holdings only for those items that we can definitively identify and match to a MARC record within WorldCat. For this to happen effectively, the ISSN is a critical match point. We’re committed to expanding the capabilities of the service to include more records and titles not already represented in WorldCat; therefore, we’re planning to add records to WorldCat that represent the non-ISSN based resources identified by our knowledge base.
