Documentary sources make most of the museum’s collection. There are more than 5000 documents with various content and degrees of importance; documents of various political organizations and businesses, and religious and cultural organizations. Mostly those that had the most positive circumstances for Jewish political and social life are from the interwar period. The content of the Holocaust documents include the reports of the USSR Emergent Commission about the crimes of the Nazis and their henchmen made against the Latvian Jews. The collection also holds reports of the Nazi German Security Police and Security Service operative group A. There are lists of prisoners of the Ghetto, lists of murdered Jews and lists of survivors. Special kinds of documents describe the events of the Jewish resistance and the support of the local populace for Jews during the war. The postwar documents include cases of soviet repressions against the Jewish activists and the Jewish underground movement. The personal funds from various periods of history are a separate chapter of the collection. They hold information about the Jewish political, social and religious personalities; Jewish businessman, doctors, scientists, philosophers and teachers, and the artists, writers and musicians. Another separate part is the personal case files of the Holocaust survivors and Holocaust criminals.
