IBM and the Holocaust: The Strategic Alliance Between Nazi Germany and America's Most Powerful Corporation by Edwin Black
Extremely interesting account of how IBM worked with the Nazis to count and catalouge the Jews. IBM maintained databases of the Jews; how many, personal data, which ones were strong enough to work, which ones should be exterminated, etc.
