I assumed this would be a 75-page ebook, but it turned out to be double that. On the other hand, it was both fun and rewarding to write, and I think it can be very helpful to aspiring ebook authors and publishers: Take Control of iBooks Author, available for $15 from Take Control Books.
Plus, there’s a free Multi-Touch excerpt for the iPad, Take Control of Getting Ready for iBooks Author, that you can download!
