Excellent resource for those of us looking for period information.
I found this site: http://www.wardmaps.com/
I have no affiliation with them. lots of good data there.
It does look like a good resource. However, the US maps are almost exclusively Northeast. Not quite as good for those modeling the left coast or the Plains or the Rockies or the South.

Well, I am a Northeast modeler.........I think mapping of the west had yet to be as thorough at the time as well........Most maps on that site don't go beyond 1922..........
