My Kindle ebook was recently published through Amazon.com. (and I have custody of the non-DRM PRC and MSWord files). Unfortunately Amazon not market through the iBooks bookstore channels. Is it possible to also market my published ebook through the iBookstore? If so, how could that be done?
Look forward to anybody's reply
You can use iTunes Producer to upload qualified/existing epubs. You'll need an account (paid and/or free) with Apple to gain access to tools and docs, etc.
iBooks Author creates special 'hybrid' epubs, but you don't need to use it to get into the store.
