Apple’s iWork and iLife suites already enable “the rest of us” to make music, movies, presentations, and more. Today, the company has added the educational textbook world to its sights, introducing an app to make creating books just as simple. With a Keynote-like interface, iBooks Author (Free) is available in the Mac App Store today. Apple hasn’t traditionally given away creative tools like this, so the fact that there’s no cost involved is a welcome break from tradition. It’s made to interact with and complement iBooks 2 for iOS devices, also announced today, and is going to be a big deal for large publishers and individual authors alike.
