Free Book-s is a search engine that scans many collections of ebooks to find free content that matches your search. I gave Free Book-s a test drive using academic terms like "physics" and terms like "fly fishing" to see what kids of results would be generated. In both cases I found Free Book-s returned very relevant results. http://www.freebook-s.com/
