Polictical history or reference? Polictical extremism in America, by John George and Laird Wilcox, published 1992, 523 pages,ISBN # 0-887975-680-2. Was a library book at one time. It has the usual library markings, some of the stamps have been marked out in green ink. On the back inside cover, the card holder has been removed and that left its mark. There is some scuffing on the cover, some very minor shelf wear along the edges of the cover. There is no dust jacket. Along the long edges of the book there are 4 little indentions. The pages are clean for a library book.
