Look for it within the next week or so.
iBooks Author is a Mac OS application that enables you to develop media-rich ebooks for iBooks on iPad. Although it has a limited audience, it makes up for those limitations with sheer publishing power. This free application makes it possible to create books that not only include fixed page layouts, but images, galleries, movies, review tests, and interactive graphics. Best of all, it features a relatively easy-to-use, intuitive interface.
We’re excited about iBooks Author, mostly because of all the great new ways we’ll be able to enhance Maria’s Guide books for iBooks readers. We’re also excited about producing a book about a brand new topic: iBooks Author: Publishing Your First Book should be available before the end of the month. We hope you’ll look for it here—and on the iBookstore, of course.
