I recently found a service which sends books in fragments so you can read them
on a daily basis or depending on the schedule you have set on their website.
The library is limited to public domain books or classical books. But can't complain bec the service is free and has been very dependable. I was able to read " The Art of War" broken into 17 fragments on my old Blackberry Phone 7230.
I'm not allowed to post links yet, the service is called "Daily Lit" I'm sure others know about this already.
