The Arolsen Archives have another collection of cards from Buchenwald which relate to prisoner labor assignments. Prisoner clerks noted the number or name of the labor detail in the lower left corner of these cards. The prisoner’s trained profession is listed under their last name. These cards are referred to as labor cards at the Arolsen Archives. It is still unclear whether they were part of the so-called “occupation card file” (Berufskartei) that was kept in the labor assignment department.
