Source materials on modern German anti-semitism, national socialism, and the Holocaust. The collection of the YIVO Institute for Jewish Research contains extensive collections of Nazi-German publications about Jews, Judaism, and the "Jewish Question". The vast majority of the collection dates from the Nazi period, although a substantial number of works were published during the Weimar Republic.

Collection content includes materials related to Nazi research on Jews and Judaism, Anti-Semitic scholarship, "knapsack books" (used to indoctrinate the common soldier), photographs and drawings, and numerous unique or rare items.
