What is EZproxy?


Access to licensed eResources is usually restricted to current Carnegie Mellon University students, faculty, and staff, and requires an Andrew ID and password to authenticate.

EZproxy is a tool that prompts CMU users to authenticate, and then grants access to eResources regardless of whether you are on or off campus. Most resources on the Databases, eResources, & Tools A-Z list use EZproxy.


How does it work?

An EZproxy prefix (https://cmu.idm.oclc.org/login?url=) is added to a resource base URL (https://search.proquest.com/advanced). 

Example link with EZproxy prefix: https://cmu.idm.oclc.org/login?url=http://search.proquest.com/advanced


After clicking a proxied link, you might notice that the URL changes, and embeds the proxy information within the URL: 


Proxy prefix change, January 2021:

CMU Libraries' proxy server changed in January 2021, and now uses this proxy prefix: https://cmu.idm.oclc.org/login?url=

The old proxy prefix was: search.library.cmu.edu/link/ or links that contained proxy.library.cmu.edu
*Please update any links/bookmarks to use the new proxy prefix, as the old ones will no longer work
