It’s often useful to be able to read scientific articles at home. My university (TU/e) offers a proxy for this: append .janus.libr.tue.nl to the domain name to use it.
It’s simpler to use with this bookmarklet. Go to an article page, enter “janus” in the address bar, and you automatically go to the right URL.
This bookmarklet is easy to save in Firefox. Right-click View through TU/e proxy, click Bookmark This Link. Right-click again and go again to Bookmark This Link to enter janus in the Keyword field.
You may also be able to use it on other browsers.
