If you have bookmarked links to Caltech Library resources using the proxy prefix https://caltech.idm.oclc.org/login?url=, you will need to update them before August 16, 2023.
Update your links with the public link generator https://go.openathens.net/generate/caltech.edu/80262336 by following the prompts and copying the generated link.
Please note that this will not work with resources provided by O’Reilly/Safari or Overdrive. Links from EBSCO, ProQuest, and Gale/Cengage will not need OpenAthens generated links, but will work if you decide to add them.
If you need assistance with links, contact library@caltech.edu.
