Nazi Germany from an Unusual Perspective

Starting to clear my desk before leaving Yad Vashem, I came across a lecture I once gave but then never published, telling about all sorts of interesting things you can find when you read boring, repetitive personal files from the ground level of Nazi persecution of the Jews. I don't expect I'll try to have it published academically anytime soon, what with my ever-widening distance from the world of academia, so I've posted it here.
