DailyLit is an interesting website that will send you small segments of a book once a day via RSS or email. The chunks are pretty short and it will probably only take a few minutes to read each one. If making time for reading books a priority, this might be a way to make an automatic, daily habit out of it.

Currently DailyLit has 901 books, all of which are free. Granted it might take you almost 2 years to read War and Peace, but there are books of all types and lengths on tap.
