OCLC Single Sign In

OCLC is working to implement a single sign in across many of its Web properties.  Currently, the user account you create manages your sign in and profile on the following OCLC web properties and resources.


WebJunction's mission is to promote learning for all library staff by providing open, affordable online learning communities.  With resources and training on library technologies, management, and services, along with public access in small and rural libraries, WebJunction ensures that public librarians are equpped to meet local needs in their communities.

Your account and profile enable you to participate in discussion groups and forums on WebJunction.


WorldCat.org is a Web portal to the WorldCat global catalog with a supporting program of data syndication that makes your library's collection discoverable virtually anywhere on the Web. WorldCat.org allows more people outside the traditional library environment to find your reliable information and assistance through the Web sites they use every day.

With a WorldCat.org account and profile, you can build WorldCat Lists, set favorites and write reviews about any of the millions of items in WorldCat.

User Support Centers

Currently, you can use this sign in for these standalone User Support Centers only:

OCLC Online Service Center

When you create an account and sign in, you will be able to order OCLC professional services for libraries, manage details about your library’s account information with OCLC and view OCLC invoices and statements.  Libraries outside of the United States, Canada and Latin America can use the Online Service Center to order Batchload Services, eSerials, Bibliographic Notification, and Digital Collection Gateway.  Please contact OCLC to purchase all other OCLC services in other regions.
