Using Electronic Resources

EZproxy Bookmarklet

How it works

Most electronic resources can be accessed from the Penn Library website through PennKey authentication. However, in cases where you go directly to a publisher's site without having logged in ("proxied") as a Penn user, you will not be recognized as having access. For these cases, the EZproxy Browser Bookmarklet will allow you to log in without first going back to the Penn Library web site. A bookmarklet is like a browser extension but more lightweight and can be used on any browser that supports bookmarks,  including mobile browsers. 

Once added you will see UPenn Proxy in your menu bar. Click on UPenn Proxy and the proxy prefix is added to the URL and the work, if Penn has access, will be accessible.

Add the bookmarklet as described below (Installing the Bookmarklet) or manually add the Penn Proxy prefix to the front of the URL. 

  • If you have the publisher's URL

Add the proxy prefix before the publisher provided URL.

A Digital Object Identifier or DOI is a persistent identifier used to identify unique objects.

Enter followed by before the DOI.
