Why didn't somebody tell me about this thing?
This is such a great idea. You find a book you want to read, subscribe to it, and Dailylit.com will e-mail you a portion of the book each day. They seem to be all public-domain works (that is, the "classics") and there's no charge at all.
Forgive me if everyone's known about this and I'm late to the party. I just thought it was a fantastic idea and a great use for e-mail.
