One of the organization’s first projects was to prepare elaborate questionnaires for groups of Holocaust survivors. By December 1945, some 3,000 testimonies had been collected, constituting one of the most significant bodies of evidence about the Holocaust gathered in the immediate postwar years. In early 1945, the commission began publishing annotated editions of these responses. It then sought monographs on the Holocaust in Poland, based largely on evidence it had gathered. By late 1947, the commission had collected about 7,300 testimonies and had published 38 books.
