Testaments to the Holocaust is the online publication of the archives of the Wiener Library, London, the first archive to collect evidence of the Holocaust and the anti-semitic activities of the German Nazi Party. It contains documentary evidence collected in several different programmes: the eyewitness accounts which were collected before, during and after the Second World War, from people fleeing the Nazi oppression, a large collection of photographs of pre-war Jewish life, the activities of the Nazis, and the ghettoes and camps, a collection of postcards of synagogues in Germany and eastern Europe, most since destroyed, a unique collection of Nazi propaganda publications including a large collection of ‘educational’ children’s’ books, and the card index of biographical details of prominent figures in Nazi Germany, many with portrait photographs. Pamphlets, bulletins and journals published by the Wiener Library to record and disseminate the research of the Institute are also included. 75% of the content is written in German.
