One of the easiest ways to find which libraries have the items you desire is through WorldCat. You can think of WorldCat as a massive library catalog. It looks up books, articles, media and more. By reading the first page of the website, you can learnmany of the ways WorldCat can help you with your research project.

You can search for titles, authors and subjects for things you're looking for just like any library catalog. Once you find and click on the item that you want, WorldCat will show you the libraries closest to you that carry the item once you put in your local zip code. You can even click through to that library's catalog, in most cases, for further information.
