The archival collection that the Institute of National Remembrance has been accumulating for twenty years constitutes an invaluable source of knowledge for research into Poland’s contemporary history, in particular the period of the People’s Poland/PRL and the years of World War II. The INR archival repository, consisting of over 90 thousand linear metres, is usually identified with paper documentation generated by the communist security apparatus. The general public is not aware that the Institute is the owner of many other historical sources, often unique, including phonographic, photographic and film. Among the latter, of exceptional worth is a film of several minutes from 8 March 1947, taken in the Rakowiecka Street prison in Warsaw, which documents the execution procedure of three high-ranking officials of the Third Reich: Maks Daume, Ludwig Fischer and Josef Meissinger. They were responsible for the organisation and perpetration of mass murders against citizens of the Republic of Poland in the years 1939–1944. All three were sentenced to death for their actions by verdict of the Supreme National Tribunal. This film of the executions of German criminals was not however intended for distribution. Contrary to the desire of the initiators, instead of a work capturing the majesty of the law and the power of the state, the shots filmed portrayed a caricatured reflection.
