I have today begun publishing all of my books on Smashwords. Don't worry, they will remain on Kindle and as paperbacks, from Kindle Direct Publishing and CreateSpace respectively. The Smashwords development will expand my availability considerably.
The process is quite time-consuming because I have to prepare each book manually. There probably are ways in which I could automate the processes, but I don't use them in case they miss something. I am quite fanatical about producing a professional document for my readers. Anyway, so far I have managed to publish 'The Planning Officers' and 'Usurper'. They are currently on sale at the Smashwords Store in every ebook format known to man (including Kindle - the Smashwords editions are slightly different from the original KDP editions, which remain on sale, although the actual text is the same). The are undergoing a review process, which will determine their suitability for the Smashwords premium Catalogue, which will see them go our on iBooks, Kobo, Nook and the Sony E-Reader, to name but four.
I expect to have all seven books listed in the Smashwords Store within two or three days. Apparently it will take a little longer for them to go out to the other retailers.
