Did you know that there is a free library catalog that allows you to search thousands of libraries catalogs all in one search? It is called WorldCat. Besides books, you can search for music CDs and DVDs—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 audiobooks. You may also find research materials such as documents and photos of local or historic significance; and digital versions of rare items that aren't usually available to the public. Because WorldCat libraries serve diverse communities in dozens of countries, resources are available in many languages.
