Brut︠s︡kus, I︠U︡. D., 1870-

This collection contains translations into German of selections of scholarly works about the Karaites. Done under orders from the Einsatzstab Reichsleiter Rosenberg (ERR), the translations were meant to assist the Nazis in determining if the Karaites were to be considered Jewish or not. The work was supervised by Zelig Kalmanowicz in the Vilna Ghetto from 1942 to 1943.

The Lithuanian Jewish Communities Collection is comprised of documents relating to Jewish cultural, religious, social, political, and economic life in approximately 150 towns in Lithuania. The bulk of the collection pertains to the period between 1919 and 1926, when elements of a system of Jewish national autonomy existed within the Lithuanian state, including a Ministry of Jewish Affairs and governmentally empowered Jewish community councils. Smaller parts of the collection relate to the periods before (1860-1918) and after (1927-1940) the autonomy.
