No idea if that was done with the JTAS Amber Zone worlds, but the first Atlas of the Imperium came out before the change over from JTAS to Challenge. That's one of the reasons I'd like to put this together so that they are all in one place and make that kind of search easier.

The file I create will be using Open Office Base, I've heard that people have had problems reading this using MS Access, so let me know if that is a problem.
