For students of history

and particularly of World War II:

Timothy Ryback's 'Hitler's Private Library'

"As Mr. Ryback aptly adjudges, what Hitler's attention to such works shows is
'Not a profound, unfathomable distillation of the philosophies of Schopenhauer or Nietzsche, but instead a dime-story theory cobbled together from cheap, tendentious paperbacks and esoteric hardcovers, which gave rise to a thin, calculating, bully mendacity rather than some profoundly grounded source of evil, less the triumph of the will than of the shrill.'"

It sounds interesting...
