Can anyone recommend a good website(s) for free ebooks?

This question is partially motivated by me wanting to share a great site for ebooks I recently found – http://www.truly-free.org/. It has quite a diverse collection and offers many titles not found on ebook websites.
Gutenberg, Google Books, and similar sites are great but I am always on the lookout for great reads by more current authors (not knocking the many brilliant classics offered free online). I realize copyright laws factor into what ebooks are available to be downloaded for free and respect authors’ work and right for compensation, but if anyone has any legit sites to share…?
