Click on the image for the DEMO books used in the presentation. There are resources, and examples of how widgets can be used in iBooks Author. The DEMO chapter contains nonsense text to show how the text flow works, but the other chapters give concrete resources for use of iBooks & iBooks Author.
Feel free to contact Stephanie Baer or Kacee Conley with questions. If you'd like access to any of our other examples, let us know and we'll contact the author for you!
