The beta process, which began in 2013 for FirstSearch, and in 2014 for WorldCat Discovery is coming to an end. On August 9, 2019, WorldCat Discovery will replace WorldCat Local.

In March 2016, OCLC announced it was keeping FirstSearch as a separate product rather than merging it into WorldCat Discovery as originally planned. In 2018, the FirstSearch interface was redesigned to give it a more contemporary look, in response to requests from the FirstSearch community. OCLC continues to enhance the technology platform that supports FirstSearch to increase security and support stability of the service and continue to monitor and change the platform as needed. Moving forward, they will continue to address changes that reflect both technology needs, feedback from the FirstSearch community, and guidance from the FirstSearch Advisory Group.

We will share important news in CDLInfo News, and on this page. When the time comes, we will work with stakeholders on updating instructional materials, announcements to users, and more.
