If you have not been interested in the early version of iBooks Author, the latest version might lure you to take a second look at it.
There are newly-added Apple templates in the categories of crafts, cooking, photography and biographies. The new portrait-only templates, which are fixed width, allow navigation, table of content, and interaction as should be available to a landscape book in landscape orientation.
On top of the existing widgets where users can include photo galleries, interactive quizzes, 3D objects, keynote presentations, and movies, there are two new widgets for improved interactivity - Scrolling Sidebar and Pop-Over. Besides those, users can embed custom fonts and have better support for mathematical expressions using LaTeX and MathML notation now. Media are automatically optimized when embedded, and iBooks Author now supports all media and audio formats supported by Quicktime.
One can always preview your book on your iPad anytime, or submit published work to Apple Bookstore after an improved workflow of automatic sample book creation and pre-publish checking.
