What do you do with an ePub book once you have created it?

Using Book Creator on an iPad is a real revelation to some teachers and their pupils.  It doesn't matter where you are: on a field trip or in a classroom, the story of the activity can easily be brought together and used to provide a simple record, prolong engagement or assess learning.

But if you are a Windows school, what else can you do with it away from the iPad itself?

Using Readium, a free app on the Google Chrome browser, can provide access to your ePubs on PCs.  It renders the book faithfully, maintaining the structure of the book as well as narration, etc.

How do you get it there? Share the book via Gdrive (if you are a Google Apps for Schools user, for example), DropBox or whatever other mechanisms you have set up and use Readium to access it.
