I gave a presentation at a self-publishing workshop last April and mentioned that if you want your indie book in iBookStore, Barnes and Noble, Sony, etc. (but not yet Amazon), then Smashwords is the way to go. You can find April’s presentation here. And, I’m embedding a quick presentation from Smashwords below that provides more detail. And, yes, my Broom books are available in the iBookStore, courtesy Smashwords!
It’s not hard. Just follow the directions step by step and you’re there. There’s nothing standing between you and seeing your manuscript become an e-book. Although Smashwords doesn’t distribute to Amazon, it’s in negotiations to do so. In the meantime, I distribute through Amazon Kindle directly.
