Arranged alphabetically into six series: Department of Defense, Hermes A-3 Missile Project, Naval Research Laboratory, Office of Scientific Research & Development, Reports, and Scientific Advisory Group. This series encompasses Houston's research and consulting for various government projects and includes reports, essays, letters, photographs, diaries and scientific essay reprints from various Japanese scientists.

While working under the auspices of the Office of Scientific Research & Development, Houston worked at Columbia University researching homing devices for torpedoes and other such underwater warfare devices. Due to the classified nature of this research, the bulk of the records in this collection pertain to Houston's continued involvement with this group after World War II and his return to California Institute of Technology. Also while working for the Office of Scientific Research & Development he worked on issues of atomic energy. Houston worked with The Scientific Advisory Group in July and August of 1947. This group, made up of six American scientists, was sent to Japan to make recommendations on the reorganization of the postwar Japanese scientific community.
