Louis L Snyder's monumental Encyclopedia of the Third Reich is an essential reference book for both professional and amateur historians of the period. It covers the period from the rise of National Socialism to the fall of the Third Reich in May 1945, but carries selected entries on the Weimar Republic which preceded Hitler, and on the Bonn Republic which succeeded him.
Drawing on his own resources as a student in Germany from 1928-1931, from the incomparable files of the Weiner Library in London, The Firestone Library at Princeton and the Imperial War Museum, the author has assembled a most remarkable source book of Germany's darkest hour.
