If you access library resources using saved links or bookmarks with "oca.ucsc.edu" in the URL, please read on—this message is for you!

The Off-Campus Access Proxy Login service (OCA) will be discontinued on December 31, 2024. This service has been replaced by OpenAthens, a new authentication system that uses CruzID. Links in UC Library Search were updated last summer, so if you're accessing resources directly through UC Library Search, you're all set.

However, if you have any saved links or bookmarks that have "oca.ucsc.edu" in them, you will need to update these links to ensure continued access. You can easily do this using the Athenizer tool.

For more details, including instructions on how to update your links, visit our Online Access from Off-Campus page.
