Welcome to WorldCat.org

In about two minutes, you can learn how to make a WorldCat.org profile, create and add items to lists, generate citations, and use facets to narrow your search criteria.

It’s a quick way to introduce yourself to the basics of searching the world’s largest collection of information about materials in libraries.

Not just a search engine—a library learning experience

There’s a lot of information online. Some of it good. Some, not so good. Libraries, though, have already put together lots of trustworthy, useful (and even one-of-a-kind) materials. WorldCat.org helps you find exactly what you need from thousands of libraries around the world. It’s a search engine for library materials: books, e-books, audio books, videos, databases, research materials and data, maps, records, archives, digitized documents, scans of rare works, photos of local historical significance, musical scores, genealogical records, and much more. As you search, you’ll get options to refine results and details about the materials you find. WorldCat.org is just the starting point—libraries are your destination. We’ll connect you to a library—maybe one that’s close by, maybe one across the globe—that has what you’re looking for.
