About WorldCat.org

What is WorldCat.org?

WorldCat.org is a great resource for locating unique, trustworthy materials that you often can’t find anywhere except in a library. And by connecting thousands of libraries’ collections in one place, WorldCat.org makes it easy for you to browse the world’s libraries from one easy search box.

During the past 50+ years, thousands of libraries have entered their information about millions of books, magazines, movies, songs, maps, genealogical records, research theses and so much more into WorldCat. And not just the physical items you could find when you visit a library, but many kinds of digital content like open-source e-books, articles, downloadable audiobooks, and photos. You can also find article citations with links to full text, authoritative research materials, one-of-a-kind documents and photos of local or historic significance, and digital versions of rare items that aren’t generally available to the public.

WorldCat.org is supported by OCLC, a nonprofit global library organization that provides shared technology services, original research, and community programs so libraries can better fuel learning, research, and innovation.

Where do I go from here?

Do a search, click on a result, and you’ll see a list of libraries that have told us they have that resource. From there, you can either directly access online content that’s openly available or click on a link for a library near you. You’ll be able to check out or reserve materials (if you’re a member) or find contact information to get more details. If what you want is available only from a library far away from you, don’t panic. Save the link to the item and ask your local library if they can get it for you through interlibrary loan.


We work with hundreds of library groups, publishers, technology providers, and other organizations to help get library resources in front of more people across the world every day. We invite you to learn more about how your organization could partner with us.
