I'm not allowed to send private msg yeat. Still discovering this amazing forum.
For now, seems it's just like you (and me) with GIS experience over here, am I wrong?.
And I Hope to change a lot of informations with you (and others GIS pros) to make wonderfull GIS interactive maps with rich details, from this artists over here.
To keep on the subject:
I'd a little post about how I'd transformed the maps into an OpenLayers GIS, but it's in portuguese only:

Try a web translator, if it's still confused I'll try to translate my self and post here too, to help this tutorial (I didn't readed it yeat, just scan and it's a great job).
Did you know the MapTiler software, to generate the tiles from the georef.images??
