The Search for Order 1877-1920, by Robert E. Wiebe (HC, 1967, first edition, autographed, $7, which is 1/3 the internet price.)
Google "Wiebe" and you get lots of sites to chose from. This is still considered to be the first political theory work on the Progressive Era's history. Following Reconstruction came years of chaos, confusion and a disintegration of American society. Wiebe would describe how a moralistic local and rural community oriented society would turn into an urban middle-class centralized one.
The Search for Order is still much read today, respected either for Wiebe's theories, or because he was the first to state his theories. Note this is an autographed copy. You can find it in the political science section, under the window between the biographies and the American history section. It well be avail. 12/23.
