English: A young man in a SS uniform examines material plundered from the library of Dr. Magnus Hirschfeld, director of the Institute for Sexual Science in Berlin on May 6, 1933. While some materials were burned immediately on the street outside the Institute, others were loaded onto trucks and carted away for sorting. Some were torched at the ceremonial book burning on Berlin's Opera Square on May 10, but selected valuable antiquarian books and periodicals were actually sold abroad, including some that were purchased by Hirschfeld himself, since he aimed to establish a new Institute in exile in Paris. The public library of the Institute comprised approximately 10,000 mostly rare German and foreign books on the topics of sex and gender.
