"(...) wo man Bücher verbrennt, verbrennt man am Ende auch Menschen."

It was from the university's library that some 20,000 books by "degenerates" and opponents of the regime were taken to be burned on May 10 of that year in the Opernplatz (now the Bebelplatz) for a demonstration protected by the SA that also featured a speech by Joseph Goebbels. A monument to this can now be found in the center of the square, consisting of a glass panel opening onto an underground white room with empty shelf space for 20,000 volumes and a plaque, bearing an epigraph from an 1820 work by Heinrich Heine: "Das war ein Vorspiel nur, dort wo man Bücher verbrennt, verbrennt man am Ende auch Menschen".
