Recently, a new tool has entered the mix that may replace many of these other tools. iBook Author is an intuitive piece of software which allows users to simply create a e-book, using text, photos, video, sound, and widgets. These features alone duplicate many of the tools already available. The end product can be read on your computer, iTouch, iPhone, or iPad.
What separates iBook Author from the rest, is that you can share your book on Apple's iBooks, for free, or actually sell it.
iBook Author is free, and available here. To create your book, there are several templates to choose from. Much of your creation can happen by literally dragging and dropping pics or video where you want, and typing text boxes where you wish. Apple's Widgets add multi-touch possibilities to your book as well, including swipe-friendly photo galleries, animations, pop-over widgets, and 3d objects. Also of significance is the built in accessibility features including voice over technology.
When your ready to publish your book, iBooks Author will hold your hand in walking you through the process. If you don't actually want to publish on iBooks, but you do want to share a book with one or a few specific people, you can export the book and then Air Drop it, Drop Box it, or email it.
A few months ago my nephew Niky wrote a short story. Over the course of a month or two I created illustrations for his story with his direction. Using iBook Author we are publishing it on iBooks. Currently it is available here. As soon as it is available on iBooks Store, I will link it here.
