I have to use two historians, and so one I am DEFINATELY using already is Kurth. The other I was thinking, and tossing between is either John Klier and Robert K. Massie. Both have differing points of view in concerns with AA, and even though Massie seems to be a little bit more commerical in his writing, he details more on AA than Klier and Mingay.
Any ideas, or should I maybe try to incorporate a bit of all, with an emphasis on Kurth?
