How to use Proxy Bookmarklet

  1. Once you have bookmarked the proxy bookmarklet, navigate to a database or webpage that is Columbia University restricted.
  2. Once you are on the page, click on your saved proxy bookmarklet, and you will be redirected through the proxy server.
  3. If your browser session was just started you'll be prompted for your Columbia UNI and password the first time.



  • The bookmarklet is compatible with most web browsers and platforms as long as your bookmarks or favorites allow javascript.
  • Saving the bookmarklet to your browser's Bookmarks Toolbar is the easiest way to access it quickly. If the Bookmarks Toolbar is not visible in your browser, you can try to enable it under the View > Toolbars menu.
  • If you are using a VPN, it may conflict with the proxy bookmarklet.
  • In some cases you may need to use the browser's "Back" button to return to the resource URL, not the vendor's login/error page.
  • Licensed content is provided by a number of vendors and some content may not be purchased directly from the source you are using. In this case you will need to start from the Libraries' website or catalog to see if we have access to this resource.
