Other sources that were used to manage DPs have also found their way to the Arolsen Archives. For example, the employees of IRO Area Team 2 in Linz (Austria) created a register of all DPs they were responsible for. They precisely noted who was currently residing in which camp, the destination of DPs who had departed, who had gotten married and who had died. When Frederick Lass left Camp Ried in August 1949 to emigrate to the USA, IRO employees crossed out his name and noted his departure date and destination country.
