Lean Library Open provides patrons with access to Open Access versions of the articles they are looking for without any cost or institution affiliation or subscription.
Open Access:
When you land on an article with a detectable DOI, we will search against our Open Access partners, Core.ac.uk and Unpaywall, and find you a possible Open Access version of the article. Once a result has been found, you will get an Open Access pop-up, which will redirect you to the Open Access location of the article. Read more here.
