Links to useful FREE library sites

Google Scholar: Probably the best way to access recent scientific literature on the internet. 

Biodiversity Heritage Library: A remarkable free online source of biodiversity publications that are out of copyright and many (e.g., KU series) that are still in copyright. I use this site almost daily. See

Internet Archive: Another remarkable free online source of publications. See I rarely start looking with this website, but I frequently end up here.
