Source of acquisition is the Bundesarchiv, Germany, Bestand ZSg.109. These records were collected by Theo Oberheitmann, editor of the newspaper Weilburger Tageblatt, and were used in one of the Nuremberg Successor Trials (vs. Weizsäcker et al.). They were purchased by the Bundesarchiv in 1961 from the Institut für Publizistik of Wilhelms-Universität Münster. The United States Holocaust Memorial Museum Archives recieved the collection via the United States Holocaust Musuem International Archives Program in Nov. 2009. The entire collection was digitized in 2012.
