This looks like quite a project: Square Dancing in Wisconsin: A Historical Perspective. It’s obviously a labor of love that will provide a valuable historical resource. The IAGSDC also has a history book, although I think it’s now out of print. It’s a collection of interviews and articles detailing the first 10 years of the IAGSDC.

I wonder how many other states or regions have written histories. I know Jim Mayo (no online presence, but here’s an article he wrote) is working on a history of Modern Western Square Dancing, and Bob Brundage has interviewed over 100 MWSD leaders for an oral history project for the Lloyd Shaw Archives. I’d love to see these resources become generally available.
