Lean Library is a free browser plugin that helps you find the easiest way to access electronic resources while you are browsing the Internet.

Just install the extension, and let it lead you to digital content available for Freie Universität Berlin or to open-access content.

When you are looking at result lists in Google, Google Scholar, JSTOR, Amazon, etc., Lean Library will provide additional results from Primo. That way, the extension lets you know directly whether you have access through the University Library.
