As an undergraduate, Lean Library has saved me countless hours of frustration from trying to access a research article only to find out that my college doesn't have access to that specific site or the article doesn't have the information I am looking for. Lean Library easily connects me to a different site with the same article if my college doesn't have access to the original site and allows me to very easily read the article! I could not imagine my life before this extension I only wish I had known about it earlier.
