Distributing E-Books from iBooks Author
Apple provides multiple ways for you to distribute the books you create in iBooks Author. But it can be confusing to understand your options — and it’s critical to understand them upfront so that you don’t choose an option that prevents you from desired distribution channels later.
If you want to sell any of your books
You must get a paid publisher account. With this type of account, you can both sell and give away your books via Apple’s online iBookstore. If you sell even just one book, all your free books must be published via the paid publisher account.
Selling your iBooks Author-created books through other venues is prohibited, although you can use the same contents and create books for other e-readers, and even for print, by using other software programs.
If you want to only give away books
If you want to give away your books, you have several options:
Create a free publisher account, which lets you distribute your books in the iBookstore. If you create such an account, you can’t sell any of your books via the iBookstore.
Export the book as an .ibooks file (choose File→Export in iBooks Author), and then distribute that file however you prefer: as a web download, via e-mail, or in some other medium. Recipients just need to drag the file into iTunes on their computers and sync to their iPad, or open the link or e-mail attachment on their iPads. Remember, you can’t charge for such books.
