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 experience. WorldCat Discovery remains the user-facing interface to WorldShare® Management Services.

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.
