Once we get past simple linear reading books, the real challenge in designing for online, ePub and print in a simultaneous design production environment is planning and executing content flows for the different presentation contexts.
There are a number of options available to create a format optimized reader experience. What works for print, does not work for e-books, especially with a text-book style document such as this exercise example, This Dynamic Earth (TDE) by W. Jacquelyne Kious and Robert I. Tilling.
This book is
available online as a web pages. It was one of the few copyright free
content sources that was adequately "textbook" for this exercise.
Unfortunately there are no print resolution images available, so both
online and print images may look a little fuzzy. But this blog is about
Simultaneous Design, not image processing!
