Take advantage of a global catalog

The Internet is the first choice for most information seekers. With your holdings and other metadata contributed to WorldCat, makes your library's resources more visible to more people on the Web. As the world's largest library catalog, it helps users find items in libraries close to them. So your reliable, verified information and personal assistance—the hallmarks of the library experience—gain greater exposure, credibility and use among people in your community and around the world.

Help users see which libraries hold the items they want

Once users have done a search on, they scroll down for a list of WorldCat-participating libraries nearby that own the item. Your library's listing shows its distance from the user's location and links to a Google Map. You listing connects users to your "Library Info" page on as well as to your "Ask a Librarian" virtual reference services and to your website's general information page, which lists locations, operating hours and phone numbers. listings make it easy to see which libraries are the closest to the user. Any favorite libraries display first in listings—marked with a red heart—regardless of location.

Share your library's holdings across the Web

Information about your library's holdings and online services is actively spread across the Web via strategic partnerships with key sites such as Google and Goodreads as well as by social and distributed Web technologies such as APIs, widgets and mobile and social apps that appeal to users, other information providers and e-businesses.

The result? Your local resources gain a global presence, become part of people's normal Web workflow and get in front of the increasing number of people who rely almost exclusively on the Internet.

Engage users where they are searching and deliver your content

Internet users don't just search, they interact with what they find. lets them build and share lists, contribute reviews, put a WorldCat search box or other widget on their personal site, use WorldCat apps in Facebook and on their mobile phone and generally spread information about library items all around the social Web.

"Although most of the collections in Anet's libraries are general in nature and serve diverse research and education communities, some of the collections - especially old and rare books - are rather unique. We want researchers from around the world to be aware of our materials and we want them to be accessible to a global research community. We see the opportunity to load our metadata in WorldCat as a great way to realise this mission."

Trudi Noordermeer
Director of the University of Antwerp Library
