Books for amazon kindle?

you can go on amazon's website and click "i want to read this on kindle" on most books that aren't on kindle. this sends a message to the publisher, but it's up to them to licence it for digital readers. I'm not sure of the legal issues, but you can directly transfer text files to your kindle from your computer, so if you have a text copy of something you want to read you may be able to do it that way
