Best Places to Download Free Science Fiction Books

After searching the web for some time, I haven't found a good comprehensive list of science fiction websites with free online books. So, I decided to make my own: below is the list of some very good collections of science fiction novels, short stories, ezines, and other sf related stuff. All ebooks are available for online reading and/or free download in various formats. This list is a work in progress, if you know any other science fiction oriented website with good amount of free (legal) content, feel free to post your comment.
