Alongside the release of iBooks Textbooks this morning, Apple has also released an app called iBooks Author. Available for free on the Mac App Store, iBooks Author is a tool that allows anyone to create a textbook, storybook, or any other kind of book with relative ease. These books aren't just text either--you can add videos, 3D objects, photo galleries, web widgets, and more. Once you're satisfied with your book, you can then export it for personal use, or publish it to the iBookstore for sale or as a free download. Check out the video above for a full rundown of how it all works.
