With few exceptions (see Bibliographical Note), the Holocaust literature is virtually devoid of mention of the Hollerith machines—in spite of its high profile display at the United States Holocaust Museum. Historians should not be defensive about the absence of even a mention. The public documents were all there, but there are literally millions of frames and pages of Holocaust documents in the leading archives of the world. Many of these materials had simply never been accessed, many have not been available, and some are based on false chronologies or appear to be corporate minutia. Others were well known, such as Heydrich's 1939 instruction on concentrating Jewish communities near railroad tracks, but the repeated references to census operations were simply overlooked.
