Too busy to make time to read the classics? Check out Daily Lit. Pick out a classic you would like to read, John Bunyan's Pilgrim's Progress for example, and Daily Lit will email the book to you in small, successive pieces (about five minutes worth of reading each email.) They divide Pilgrim's Progress into 80 sections. If you choose to have it sent to you five days a week you will finish the book in 16 weeks; sooner if you use the "Click here to receive the next fragment immediately" at the end of the email. This is a creative way to include some reading into your intellectual/spiritual diet that you might otherwise skip. If you have a Blackberry, Treo, etc. this keeps your book with you at all times.
You can suspend a book you are currently reading, or receive more than one book at a time.
I am currently reading Dante's Inferno. A few I plan on hitting next are: Melville's Moby Dick, Mary Shelley's Frankenstein, Twain's Adventures of Tom Sawyer, The Works of Edgar Allen Poe... and a lot more. So far I am loving Daily Lit.
