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. 303/XIX. In 1950 the Centralny Komitet Żydów w Polsce (CKŻP) in Poland was liquidated and its archives were transferred to the ŻIH. This collection is a substitute of the collection acquired in the Musuem in 2005, RG-15.105M. Due of the re-arrangement of all files in the ŻIH, a new set of microfilms were sent to the Museum. The United States Holocaust Memorial Museum Archives received the filmed collection via the United States Holocaust Museum International Archives Project in Dec. 2013.
