control of an International Commission under the direction of the
International Committee of the Red Cross (ICRC), where it remains today.
Records in the custody of the ITS were gradually accumulated at Arolsen
from numerous sources. A four–volume Catalogue of Records held by the
International Tracing Service of the Allied High Commissioner for Germany
at Arolsen (1954) provides a general inventory of all records held by the ITS
as of December 1953. Most “Concentration Camp Records” (described in
Volume I) were originally seized by the Allied western armies and assem­
bled at Arolsen after their use by the International Military Tribunal at
Nuremberg and Allied War Crimes Commissions. Concentration camp
records designated “postwar” were assembled from Allied military agencies,
UNRRA, IRO, and other sources. Mauthausen Concentration Camp records
are described in Volume I of the ITS catalogue under four categories: col­
lective records, individual records, films, and miscellaneous records of gen­
eral or historical interest. Records of Foreign Countries (Austria) described
in Volume IV may include information on camp survivors.
