Hi Glenn. I'll have a look at the CB packages and get back to you about the map.
The app currently doesn't have any book intro-data in it. This was a decision I made when I first started building the system to extract and appify the information from our desktop-publishing documents years ago.
The reason behind it was that I didn't know how to present the information to the user in the app in a simple way.
I regret this decision now, and plan to fix it at some point, but it won't be for a while yet I'm afraid as we have a number of higher-priority things we need to sort first.
