I have to recommend the DailyLit where you can sign up to read short chunks of public domain literature sent to you daily by e-mail. I am signed up to Bleak House (because this is the only way I'll get through a Dickens novel), The Time Machine (because I like Wells) and Notes from (the) Underground (because it sounded strange - and it is).
A quote from Notes from Underground:
"I am forty years old now, and you know forty years is a whole lifetime; you know it is extreme old age. To live longer than forty years is bad manners, is vulgar, immoral. Who does live beyond forty? Answer that, sincerely and honestly I will tell you who do: fools and worthless fellows."
