I am trying to add a title to a collection and am getting an error message: "entry already exists by Uid".

  • You are receiving an error that adding a title to your local collection failed
Applies to
  • WorldShare Collection Manager

If you are adding the title with the "Lookup by OCN" feature, try instead adding the title manually.

If this does not work, contact OCLC Support.
