WorldCat is the largest library network in the world. WorldCat libraries are dedicated to providing access to their free resources on the Web, where most people start their search for information. WorldCat's coverage is both deep and wide. You can search for popular books, music CDs and videos—all of the physical items you're used to getting from libraries. You can also link to many new kinds of digital content, such as downloadable audiobooks you can listen to on many portable MP3 players. You may additionally find authoritative research materials, such as documents and photos of local or historic significance; abstracts and full-text articles; and digital versions of rare items that aren't available to the public.
- Available to everyone.
