I love books. Free books are even better, as I can indulge both my bibliophilia as well as warm my tight-fisted little heart. If you, too, have a hankerin' for free-for-the-download books,
Project Gutenberg is up your alley.
For instance, say you need a text copy of the
US Constitution? Or the
Bill of Rights? Project Gutenberg will even allow you to download all 70,000 of their titles automagically with a GNU/linux tool such as wget...as long as you are nice about it and follow their rules.
