There are only two eBook formats, and they are both ePubs. One is fixed layout (this format is going out of favor) and the other is reflowable text. (Kindle now requires a reflowable ePub format.) When your ePub editions are ready, you’ll be able to sell them online through booksellers such as Amazon (Kindle), Barnes & Noble (Nook), iTunes (iBooks), and Chapters-Indigo (Kobo). You’ll register with eBook vendors, enter into a contract with them, and upload the appropriate edition of your eBook. Your readers will be able to find your book online, purchase it, and download the appropriate edition for their eReader.
Did you know that you don’t actually need a dedicated eReader to read eBooks? You can read eBooks on whatever electronic device you have. For example, if you have a computer, tablet or smartphone, you can download a free eReader or app to read Kindle or ePub eBooks. So anyone with a computer, tablet, or smartphone can read eBooks too.
After your print book goes to press, we’ll be happy to recommend a service to convert your book to ePub and Kindle editions for you.
