Apple Reveals New Service for Authors to Sell Their Books Directly in the iBookstore →

David W. Martin, in Mac|Life:

Apple sent us an e-mail today with details on how someone could sign up to sell their own books in the iBookstore. Their books would have to adhere to these criteria: each one would need to have a 13-digit ISBN, be in ePub format, validate against epubcheck 1.0.5, and contain no unmanifested files

There’s a few other conditions, but with iPhone OS 4 including iBooks, seems like a very easy way to tap into a huge market.
