This collection has two distinct subjects. A small number of photographs deal with videotape and video voice technology. While the majority of the images deal with the creation and testing of Home Fax. The home fax photographs are mainly basic images printed on plain paper when the system was being tested. There are also photographs of the hybrid television/fax machine showing how it could be used in the home.

Thirty-four of Houghton's lab notebooks (1940-1966) can be found in Record group 26.
