Of Himmler's three-hour speech of 4 October 1943, 115 pages of the final typewritten edition (one page was lost) were discovered among SS files and submitted to the Nuremberg Trials as document 1919-PS.[9] On day 23 of the hearing, a passage (which however did not concern the Holocaust) was read out.[10] A live recording of this speech survives, allowing for the differences between the spoken and the copyedited version to be examined.
