This report is based on findings from newly-declassified decades-old Army and CIA records released under the Nazi War Crimes Disclosure Act of 1998. These records were processed and reviewed by the National Archives-led Nazi War Crimes and Japanese Imperial Government Records Interagency Working Group. The report highlights materials opened under the Act, in addition to records that were previously opened but had not been mined by historians and researchers, including records from the Office of Strategic Services (a CIA predecessor), dossiers of the Army Staff's Intelligence Records of the Investigative Records Repository, State Dept. records, and files of the Navy Judge Advocate General. This is a print on demand report.
