Seeing NHAIS holdings in WorldCat

While WorldCat.org allows you to see materials held by libraries around the world, for many years you couldn't see NHAIS holdings there. Now an extra click will show you if the NHU-PAC (the union catalog in the NHAIS ILL System) has a copy of the OCLC record you're looking at in WorldCat.

WorldCat search results show you a list of "Featured libraries" that hold the material listed. Click on the "All libraries" tab to see more locations, including the NHU-PAC (listed as "NHAIS"):

You may see a few libraries that participate in the NHAIS ILL System, including the State Library, listed separately. That's determined by the kind of account these institutions have with OCLC.

Keep in mind that the presence of a record in the NHU-PAC doesn't guarantee that a library in the state has a holding for that title. You need to use the NHAIS ILL System to see that. Also be aware that there's always a lag, usually a few hours, between when a record is downloaded from WorldCat and when it's uploaded to the NHU-PAC. During that time, WorldCat.org will show that the record is in the NHU-PAC even though it isn't quite there yet.
