Longman Companion to Nazi Germany [PDF ebook] 

Here is a wealth of factual and interpretative information about Germany between 1918 and 1945. Designed for maximum practicality, it sets the Hitler years in their wider context, with most sections spanning the Weimar Republic and the rise of Nazism as well as the Third Reich itself. In addition to political chronologies and anatomies of the Nazi party and the police state, there is detailed information on economy, society and culture; diplomacy, rearmament and war; and racial politics and the Holocaust. Biographies, glossary and a rich annotated bibliography complete an invaluable study aid.
