The free version of WorldCat can lead you to many of the same features as the subscription version.
Finding Subject Headings
We’ve heard from a number of people stating that they used WorldCat (WC) for obtaining subject headings. LOC subject headings are freely available on the WC record.

Obtaining the results list
Choose the title that best fits your needs and click on the title itself to see the item record (not the MARC record).
Viewing the item record:
Note that not all library catalogs holding this item will offer a MARC display. If one library does not, check with another library on the list. When you click on a library holding this title, you should be taken to exact record in the library’s catalog. If you are not, back up a page and choose a new library record to view.
Remember that only OCLC member libraries are shown on this list. If you are looking for a title to interlibrary loan, always check NHU-PAC first. Libraries located closer to your location are shown at the top of the list.
