These records were maintained by the University central offices administering contracts (especially the University Treasurer) and by individual laboratories or investigators; they were gathered at the end of hostilities by the University's War Archives Office. In addition to records relating to Army and Navy training (which included electronics and similar programs), there are procedural and policy documents on contracts especially with the Office of Scientific Research and Development (OSRD), espionage and patent agreement forms, and subcontracts for the Radio Research and Underwater Sound Laboratories. Also available are contracts, correspondence, notebooks, and especially technical reports for the Electro- and Psycho-Acoustics laboratories and for a number of smaller projects in medicine, chemistry, physics, engineering, and other fields.
