Set up "deep" links from WorldCat.org to your online catalog

Our tutorial explains how to figure out the URL syntax (link structure) that gets information seekers from a WorldCat.org item record to the same item record in your OPAC. You'll also learn how to register this linking syntax in the WorldCat Registry.
