Users can create private or sharable lists of up to 500 items for personal, research, educational, or promotional purposes.

Prominent fulfillment options
Item pages feature a "Borrow" link that connects to the nearest holding library. Full listings for all libraries with the item are also displayed, along with purchase access options.

Citation tools
Users can generate and copy bibliographic citations for a single item or all items in a list using common citation styles.


Transform lives, one search at a time

WorldCat.org is grounded in real people and their stories. It starts with a search but can lead to life-changing discoveries. And your library is more likely to be part of that journey when your collections are included in WorldCat.org.

“[WorldCat.org] is incredible—the power of having all that knowledge easily accessible. So proud of OCLC for the foresight and staff abilities to take this giant leap forward.”

—Public library director

“Nearly everything I’ve ever searched for is there. WorldCat is this big base of everything all in one place—obscure books, popular books, movies, music, everything.”

—Assistant Professor


Extend reach and influence of your collections

With more than 70 million visits annually, WorldCat.org connects your library to people who may never otherwise visit. Partner websites like Google, Wikipedia, and Goodreads help spread the word about your unique local content even further.


Deliver greater access to information

WorldCat.org represents the world’s largest library community on the web with access to billions of items from thousands of libraries worldwide. Together we advance the collective mission of libraries to provide equal and equitable access to information.

“I tell everyone about WorldCat—and I love the excitement people feel when they realize that WorldCat will allow them to look up that book, movie, podcast, or transcript in their local library!”

—Artist & business owner

Maximize your institution’s visibility on WorldCat.org

Does your library participate in our web visibility program? If so, a small time commitment ensures that your library and its collections are presented accurately on WorldCat.org and that more information seekers connect with your library from the site.

Step 1: Refresh your profile in the WorldCat Registry

This profile determines how your name and location are displayed and enables people to access your catalog from WorldCat.org.

Step 2: Update your holdings in WorldCat

Accurate holdings in WorldCat ensure people can find and access all of your resources. You can request a streamlined holdings update at no additional cost with any OCLC cataloging subscription.

Step 3: Build library lists

Create a WorldCat.org staff account and build lists to highlight resources in your library’s collections.

Options for every kind of library

All OCLC cataloging members receive a basic institution listing on WorldCat.org. Additional web visibility subscriptions are available to help you reach more people.
