Although many journals are only available to those with a subscription, an increasing number are now making some or all of their content freely accessible, or 'Open Access'. This means that our subscription database are not the only place you need to look when searching for resources. Find out more about how to search for open access content using this handy guide.

The Lean Library Button
Compatible with most browsers, Lean Library is a browser extension that will automatically detect when you have access to something. This access might be provided through the University of Cambridge's subscriptions, or it might be an Open Access version. Either way, this will reduce the need for hours spent trying to log in to different websites or hitting paywalls and will give you quick access to what you need.
