WorldCat is the world's largest network of library content and services. WorldCat lets you search the collections of libraries in your community and thousands more around the world. You can search many libraries at once for an item and then locate it in a library nearby or request an interlibrary loan.
WorldCat is a catalog of more than 49 million books, serials, audiovisual media, maps, archives, manuscripts, scores, and computer files owned by more than 9,000 OCLC member libraries around the world, including UW-Madison and the Library of Congress. More than 400 languages are represented.
