Project Gutenberg
Ever wished you could read a downloaded Sherlock Holmes story in bed instead of in front of your computer? Now you can : Project Gutenberg offers electronic versions of texts whose copyright has expired; almost all major classics (and more) are covered. Unfortunately, these texts come as plain ASCII, which is very platform-independent, but also a pain to read. With a little LaTeX formatting, maybe these things can be reformatted to someting more readable. I noticed also that Debian includes a Gutenbook program, which allows you to browse the Gutenberg library online.
