Why, with hundreds of Hitler biographies, had not more scholars visited the Third Reich Collection? It is referenced by none of the leading Hitler biographersnot Alan Bullock, not John Toland, not Joachim Fest. Ian Kershaw, whose recent two-volume Hitler biography has won international acclaim, told me in the summer of 2001 that he visited the collection once, in the early 1990s, but "decided against any consultation of the volumes in it, and in the event did not refer directly, so far as I recall, to the collection in my biography." In retrospect, Kershaw concedes, he should probably have at least mentioned the collection in a footnote.
