The Technical Reference Files comprise an artificial collection that currently contains 1,900 cubic feet of aviation and space related materials, organized in 22 subject series. File materials include photographs, press releases, clippings, correspondence, reports, and brochures, on individuals, organizations, events, and objects.
The majority of the Archives Department's public reference requests can be answered using material in these files, which may be accessed through the Reading Room at the Steven F. Udvar-Hazy Center in Chantilly, Virginia. More specific information can be requested by contacting the Archives Reference Desk.
List of Series
