For those who do not have a Kindle, iPad or other such device, you can download free Kindle software to read Kindle books on your regular computer. You then have access to Kindle books.
With that said, I find Amazon's interface for managing those books to be archaic. You must deal with each one separately and wait for page updates before you can process another book. I realize that there stuff going on behind the scenes, but those could be done in a batch, rather than making me sit and wait. Sorry for venting, but I got frustrated with this the other day.
