WorldCat is the world’s largest network of library content and services. WorldCat libraries are dedicated to providing access to their resources on the Web, where most people start their search for information.
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 discover many new kinds of digital content, such as downloadable audio books. You may also find article citations with links to their full text; authoritative research materials, such as documents and photos of local or historic significance; 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.
