While the Nazis did not write down the names of those executed in the gas chambers at places like Auschwitz, they did keep detailed records of millions of others who died in the camps. Their names are listed in notebooks labeled "Totenbuch," which means "death book." The names are written here, single-spaced, in meticulous handwriting.
"Here we see the cause of death: executed. And you can see, every two minutes they shot one prisoner," Jost explains.
"So they shot a prisoner every two minutes for a little over an hour and a half?" Pelley asks.
"Yes. Now look at the date: it's the 20th of April. That was Adolf Hitler's birthday. And this was a birthday present, a gift for the Führer. That's the bureaucracy of the devil," Jost says.
The devil is in the details - the smallest details. Pelley and the 60 Minutes crew were amazed to see the Nazis kept records of head lice.
"You can see the names and numbers of each prisoner, and the amount of lice that were found," Jost says.
The Nazis couldn't have disease spreading among slave laborers. "You can see he was a perfectionist. He even put down the size of the lice. Large, small or medium-sized lice," Jost comments about the Nazi lice inspector.
Paul Shapiro helped pry open the archive. He's Director of Holocaust Studies of the U.S. Holocaust Memorial Museum in Washington D.C.
"I'm curious. Why did the Nazis keep all these records? If they were gonna murder these people anyway, why keep the paperwork?" Pelley asks.
"Because they wanted to show they were getting the job done. So, in terms of people whose destiny was to be murdered, recording how well that was being done was very important," Shapiro explains.
