About WorldCat.org

What is WorldCat.org?

WorldCat.org is a resource for locating unique, trustworthy materials that you often can’t find anywhere except in a library. By connecting thousands of libraries’ collections in one place, WorldCat.org makes it easy for you to browse the world’s libraries from one search box.

In the past fifty years, thousands of libraries have represented their collections in WorldCat. Today, you can search WorldCat in nearly 500 languages to find physical items like books, audiobooks, maps, musical scores, and recordings, along with electronic items like ebooks, e-journals, articles, and digital images you can access online.

Search WorldCat.org for information on almost any topic: from science to cooking to history and genealogy. Here, you'll find out which libraries own bestsellers and one-of-a-kind items like family histories, photos, and other unique materials. A search on WorldCat.org delivers a single set of search results that integrates information about relevant library resources to support your information needs.

WorldCat.org is provided by OCLC, a nonprofit global library organization that provides shared technology services, original research, and community programs so libraries can better fuel learning, research, and innovation.


What is WorldCat Find?

WorldCat Find is an extension of WorldCat.org as an app, enabling anyone to search the collections of thousands of libraries represented in WorldCat. This app is designed with mobile users in mind, focusing on connecting people to libraries and their collections. It enables users to search WorldCat.org to identify all formats of library resources with search results that highlight libraries closest to them. Additional functionality will be added to the app over time.

In its initial release, WordCat Find is available with an English language interface to users in the United States. You can download WorldCat Find from the Apple App and Google Play stores.


Where do I go from here?

Search, click on a result, and you’ll see a list of libraries that have indicated they have that resource. From there, you can either directly access online content or link to the catalog of a library near you for information about how to get the item. If what you want is available only from a library far away from you, don’t panic. Save the link to the item and ask your local library if they can get it for you through interlibrary loan.
