If you are a member of Ludwig-Maximilians-Universität or Technische Universität in Munich and retrieve lots of journal papers behind paywalls this bookmarklet might make your life easier: 

ToDocWeb

Drag the link into your bookmarks toolbar and click on it every time you encounter the paywall of a university-subscribed journal. On click the bookmarklet transcribes the URI and reloads the page via the LRZ DocWeb webproxy which gives you access to most journals (you will need to log in). This without a VPN connection or traversing Elektronische Zeitschriftenbibliothek first when you start DocWeb from the LRZ homepage.
