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 imienia Emanuela Ringelbluma (ŻIH), Sygn. 201. The cards were rescued by unknown person, documents contain obvious signs of damage from fire and therefore were not microfilmed (the pages are very dark and partly burnt). The United States Holocaust Memorial Museum Archives received the collection from the Ż̇IH via the United States Holocaust Museum International Archives Project in Sep. 2007.
