Ever heard of Project Gutenberg? They offer, among other things, text versions of books whose copyrights have expired, and so are now in the public domain. The site is easy to navigate and the files they offer are pretty light, so if you ever want to read a classic now!, or need to check some reference, and don't have the book on hand, this should be your first destination.

Right now I'm reading their copy of Jane Eyre (right click and choose "Save Target as". This will download a zipped 406 KB htm file of the book to your hard disk).
