Good Online Sources for Free Books?
hydopower asks: "I recently stumbled upon a collection of online libraries. This was fascinating to me, but too many of them cost money or offer Google Print-like limited functionality. I decided to put together a list of sites that offer free books in a format that would allow a person to actually read through them. As Slashdot readers are known for being well read and for enjoying free things, I figured I'd tap into the knowledge pool here. Any suggestions?"
