Translating iBooks Authors projects into ePUB projects without using another program?
I have several iBooks author projects that I have completed and some are up on the iTunes Store. I'm wondering if there is there another way without any extra work (re-creating in another program) to use the same projects created in iBoopks Author to be used as an EPUB for other companies such as Amazon, and Barnes & Noble's or others?
If not what is the easiest way of doing it? And what program would be best use?
I want my e-books to be available in every venue not just Apple. Want to maximize sales.
Thanks for any help anyone can provide.
