Collection Manager can manage WorldCat holdings set by other services
Collection Manager is OCLC's recommended method for setting holdings on e-resources because it makes it possible to dynamically represent your subscription access as it changes over time.
Collection Manager can take over WorldCat holdings set by another process. If at any point you disable WorldCat holdings within the collection or a title falls out of your collection, Collection Manager will remove the WorldCat holding.
However, Collection Manager will NOT remove WorldCat holdings for titles on which you have an LHR attached. Collection Manager cannot remove LHRs and an LHR cannot be on a record if no holding is set on the record. You will need to remove both the LHR and the WorldCat holding via another process.
Timing for setting holdings in WorldCat
After you select a knowledge base collection, it takes 24-48 hours to set holdings on titles in WorldCat.
