A while back, Amazon used to sell a whole lot of e-books and documents, much to my delight. Then one day they stopped.
Thankfully, now they are starting to carry them again, in a Kindle Store. I am guessing that a Kindle is a particular type of reader, that only uses a certain format of e-book.
I don't know much about it, because I am still a more old fashioned ebook reader. I read the pdfs ony my computer. LOL
All of my Renassance E Books titles are now live in the Kindle Store. A quick link is:
I am hoping that soon other titles of mine (with other publishers) will also be available there.
