Need a list of all books available in Kindle website Amazonals XML file or text file

I always think of my mother for Mother’s IPAD, but do not use the Kindle 2, why not look good. I guess with IPAD zoom-in functions, brightness and color pages, they will be able to make good use (as in the situation for your laptop was old!). Who knows if all the books purchased for their Kindle on IPAD is what they are, can transfer?

Is there a site where you can download books on my computer that I did in my Kindle and do not want you to pay? I do not mean classic books. I think recent bestseller like Harry Potter, Twilight, etc.
