There's something to be said for groups like this one and Standard eBooks (mentioned elsewhere in this thread) doing some work to clean up and beautify public domain books like the ones in Project Gutenberg. Even Standard eBooks mentions that their books are all sourced from Gutenberg.
This group seems much less complete than SE, and in my opinion, they're not nearly as nice looking. I think that's more a matter of personal taste though.
