I have had several readers peruse my site looking for information about Project Gutenburg. I blogged about the non-profit last month after I read an article in the Boston Globe about their upcoming free eBooks event. (See first entry at Write Now: Free Books! Gutenberg Project.)
They have successfully launched a month-long program called the World ebook Fair allowing readers to download books at http://worldebookfair.com/. The extended list of free ebooks will be available until August 4th.
Volunteers have scanned the books, many of which are classic titles, and you can access them as pdf files or html files. Some texts are also available in mp3 format. There are amazing titles available, including some children's books, that you can easily download and print (a color printer would be nice for the illustrations).
The site offers you free ebooks, so I hate to complain about its user-friendliness. It takes patience to navigate through the heavy text and various databases. The effort, however, is well worth the reward.
