WorldCat is the world's largest library network!

WorldCat libraries are dedicated to providing access to their free resources on the Web, where most people start their search for information.

At the heart of WorldCat is a database of information about the things libraries own that is constantly updated by information professionals. Whether you're searching for something yourself or a librarian is working on your behalf, WorldCat makes it easier to find and obtain reliable, validated 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. Because WorldCat libraries serve diverse communities in dozens of countries, resources are available in many languages.

This Web site lets you find an item of interest and then locate a library near you that owns it. WorldCat search results usually link you directly to the item record on the library's Web site, and often point to the library's other online services, including "Ask a Librarian." The library's Web site may allow you to join a waiting list, reserve an item, check it out and even have it shipped or delivered. These services will vary from one library to another, and a login associated with an active library membership is commonly required to use them.
