Using EZProxy to Create Links to Library Resources

Library resources are proxied in order to properly authenticate CU Anschutz students, faculty, and staff. A proxy forces the user (whether off campus or using the campus WiFi) to authenticate as an active CU Anschutz student, faculty, or staff member in order to access library materials. This makes sure only our users have access.

Here is the CU Anschutz Medical Campus Strauss Health Sciences Library's proxy prefix:

From off campus, you may notice a proxy prefix on URLs for licensed resources.
For example, this link to Web of Science:

  • This tool requires JavaScript enabled in your browser to work
  • Always test your links before sharing

3. Copy, use, and share the resulting link

URL Encoding

As you look at URLs for library resources, you will typically see many encoded URLs (these typically have a lot of % signs and other characters hard for us to read). For example the text string http:// may show up as http%3a%2f%2f.

If you want a shorter a URL there are many great, free websites (like Meyerweb URL Decoder/Encoder) that can decode or encode URLs as you like. Although encoding is often done for web security reasons, for most end users, URLs whether encoded or not should not affect the proxy function (if proxy is included on the link) nor should encoding affect the ability of URLs to link correctly to their destinations.

URL Shorteners

URL shorteners (such as and are really just aliases for real URLs. They can be used for proxied URLs, however it should be noted that "URLs are not forever" and shortened links may provide even less information for users if and when the link fails than "real" unmodified URLs.
