"Nazi Germany sought control over people's beliefs, not just their bodies and territory. From the 1933 state-sanctioned book burnings in Germany to the purging of libraries across Europe as nations were conquered by the Nazis, "un-German" reading material was threatened with extinction. The scale of destruction was impressive. By V-E Day, it is estimated that Germany had destroyed over 100 million books in Europe."
