WorldCat Discovery

Connect your users to the information they need.
Connect your library to the world.

Both FirstSearch® and WorldCat Discovery will continue to be offered separately. Access to the current version of FirstSearch will continue as we work to deliver critical functionality to WorldCat Discovery and finalize details to bring all FirstSearch users a new and improved WorldCat search experience. WorldCat Discovery remains the user-facing interface to WorldShare® Management Services.

At a date yet to be determined, PiCarta will be integrated in WorldCat Discovery, and WorldCat Local will be replaced entirely.

Additional details will be shared as they are confirmed. To receive ongoing updates about enhancements to the WorldCat Discovery service, register for Discovery and Reference email updates.

Search WorldCat, the world’s most comprehensive library database

Identify resources at your library and in the collections of the world’s libraries. Library users and staff use WorldCat Discovery to search the WorldCat database of electronic, digital and physical resources; to identify materials they need and to find out where they are available.

Be visible where users start their search

WorldCat Discovery connects users back to your library from WorldCat.org™ and more than 50 popular consumer websites, such as Google, Goodreads and Wikipedia, when your library uses an OCLC Cataloging Subscription to represent its collections in WorldCat.

"The major feature of WorldCat Discovery Services as a discovery tool is the global scale in which this service can help librarians. This type of tool has long been a dream of librarians and is now available and is particularly suitable for our institution."
