While waiting for our ArcGIS 9.2 cd’s to arrive I had a look at the online code for the 9.2 version, DS Map Book. It looks like the only significant changes are the copyright and license header. Unfortunately the actual license text does not seem to be available (the path in the header is relative). As soon as tech support sends me the full text and I’m confident the changes don’t scupper the arcmapbook project I’ll merge the changes in.
Update: done.
