What is a proxy?

In library jargon, a "proxy" is a system that allows off-campus users to authenticate and use electronic resources (electronic journals, databases, etc.) as if they were on campus.

Most electronic resources use IP address to authenticate the end user. Colorado College's campus IP addresses are registered with our various e-resource vendors such as JSTOR, Sage journals, etc. When on campus, if you go to JSTOR, JSTOR will recognized your computer or device's IP address as one that's allowed to access the database.

When not on campus, you must use a special link that directs you through the proxy system. The proxy makes sure you're a legitimate CC patron, and then passes you through to the e-resource as if you were on campus.

For more information, see About EZProxy from our provider, OCLC.

EZProxy - what's different from the old system?

For most users, you will now see the single sign-on login. Use your Colorado College username and login (NOT your library login!)


EZProxy is better supported than our old system, WAM Proxy. You should see improvements in article linking and fewer errors. Also, browser problems should happen less frequently. Please report errors to Tutt Library Troubleshooters.
