New documents came out after the book was published that showed that IBM had specific punch cards for each concentration camp, each reason (homosexual, Jew, antisocial, gypsy,etc.) and for manner of death (natural causes, suicide, death by gas chamber).

The SS had to be trained, the machines had to be maintained, and the cards had to be updated. IBM engineers were on site at each concentration camp throughout most of the war.
