Obfuscated. A perfect word. It's bizarre you can find detailed records of all sorts of things before and after WWII... But during that time there's lots of blank spaces and missing data.

Ever try to find a list of the rank and file SS? Or verify a person who served in the Wermacht? Or a list of Jewish names who were incarcerated in camps, or during a specific timetable? If the data is out there, it's NOT in digital form... It's like it's being purposely hidden. It's like they don't want you to have ready access to that info for research.
