For years I've used Travel Guides as a source of research. It's a great snapshot of a state, usually gives you a list of historical sites and a little about each and often includes a driving map. I've found a site that offers lots of these State Tourism/Travel Guides for FREE. I have a file that I keep all of these in for Future reference.
