House Built on Sand: The Conflicts of Germany Policy in Russia, 1939-1945

Published in 1960, this book stands the test of time. The author used many of the best primary sources of his day. Many of these same primary sources are, for some reason or other, dispensed with by many of todays historians. That being said, there are very few decent books on the German Occupation policies in Russia during WWII, and this book still remains near the top. Highly recommend.
