Forms part of the Claims Conference International Holocaust Documentation Archive at the United States Holocaust Memorial Museum. This archive consists of documentation whose reproduction and/or acquisition was made possible with funding from the Conference on Jewish Material Claims Against Germany. Source of acquisition is the Żydowski Instytut Historyczny im. Emanuela Ringelbluma (ŻIH), Sygn. 204. These documents were collected in the Bialystok Ghetto and subsequently buried outside its boundaries. They were found in summer 1945 by Dr. Lew Blumenthal, who delivered them to the Central Jewish Historical Commission in Łódz in April 1946. Originals are located in at least two Israeli archives: Yad Vashem and Kibbutz Lohame Ha-Getaot. The United States Holocaust Memorial Museum Archives received the collection from ŻIH via the United States Holocaust Museum International Archives Project in July 2009.
