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

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.
