Proxy Bookmarklet

Proxy Bookmarklet

If you often do your research from off-campus, we recommend you install the proxy bookmarklet on your browser's bookmarks toolbar. The bookmarklet lets you log into the proxy without having to browse from the Columbia University Libraries website.

Installation Instructions

Add this link to your browser's favorites or bookmarks:

To add a bookmark you can:

  • Drag it to the browser's toolbar or bookmarks folder
  • Right-click and add it

On Safari or a touch device:

  • Create a bookmark but edit the bookmark's url to contain the following code instead of a web address:


You might see a security alert that the "favorite may not be safe", although it is. Click "yes" to continue.



  • The bookmarklet is compatible with most web browsers and platforms as long as your bookmarks or favorites allow javascript.
  • If the links toolbar is not visible in your browser, you can try to enable it under the View > Toolbars menu.
  • 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.
