The Nazis were notorious for maintaining detailed records of nearly everything they did, including illegal and horrific actions like the internment and eradication of Jews and other “undesirables.” In addition, political prisoners and prisoners of war entered the concentration camp system across Germany and occupied territories in eastern Europe. As prisoners entered the camps, they were issued numbers. Information was written next to each number to identify the prisoners including full names, birthdates, where they were born, and from where they came. Markings made later on some pages denoted prisoner releases and deaths.
More information about many of the concentration camps is available within Fold3's Holocaust Collection page relating to Concentration Camps.
