Lean Library Access
Do you use Browzine, EndNote Click, Readcube or PaperPanda? Then Lean Library Access is for you!

Get easy access to your library’s article and ebook e-resources directly into your browser.

The extension will notify when you are on a website that contains material your library can give you access to. A single click will redirect you to this content, no paywalls, no multiple log-ins. The browser extension simplifies searching for relevant sources and facilitates quality study time. A few quick clicks will get you started.
