This morning I made some changes to our WorldCat Local and WorldCat Discovery Services search configuration. OCLC suggested we make these changes to improve the accuracy of our holdings on search results and eliminate some conflicts that were causing problems. I’ve waited until this week (intersession) to make the changes in case they cause any unexpected problems.
Basically, only articles that are available in full text or fall within our print serial coverage according to the WorldCat knowledge base will appear as held by UTC. All other articles will appear as held by Libraries worldwide.
Please let me know if you notice any weirdness or problems with WorldCat searches.
