On September 20, 1945, President Truman issued an executive order terminating the OSS, effective 1 October. In the few days remaining to the agency, General Donovan ordered Lt. Edwin J. Putzell to assist him in microfilming select documents from Donovan's safe files for his own action and personal use. Donovan and Putzell worked, under pressure of time, with a Kodak Recordak Camera to produce 131 rolls of 35mm microfilm from the records of the Donovan files.
You can find the summary of the contents of those microfilms here - not only is it a good place to look for other reference material, the summary itself makes for fascinating reading and shows just how many pies the OSS was trying to stick its fingers in by 1945.
