Melvyl switched to WorldCat Discovery
June 17, 2019

Melvyl’s long-awaited switch to WorldCat Discovery, the Online Computer Library Center’s (OCLC) newer discovery user interface, launched on Monday, June 17, 2019.

Melvyl is the discovery platform for the University of California libraries.

As the world's largest library catalog, WorldCat helps users find items in libraries close to them and makes the UCR Library’s resources more visible to people on the Web.

What does it mean to faculty, students and staff to make the switch?

Library users will see a new interface. WorldCat Discovery has made many improvements in the user experience, including:

  • newer technology infrastructure, which supports ongoing expansion and increased operability with other services
  • interface automatically adapts to user devices, including smartphones, notebooks, laptops and desktop computers, to give people the same experience regardless of device. A new search algorithm delivers more relevant search results than the previous interfaces
  • Library staff can better support interlibrary loan, reference and collection development

Technically, what does it mean to make the switch?

Basically, it’s changing URLs. Users  who have Melvyl URLs listed on a department or course website or course management system will need to update their links or bookmarks.

The updated link for UC Riverside users is:
