However, many of the images in the Dryden Gallery are available in a large, high resolution version for the purpose of high quality printing. NASA images may also be purchased from several commercial sources. NASA Headquarters Public Affairs Office maintains a list of sources of NASA images available. The NASA Dryden Flight Research Center does not normally have such drawings available, but frequently the manufacturer of the aircraft will have at least drawings of its recent models. The address of the manufacturer can be found in such sources as the World Aviation Directory , which is available in many libraries.
Many manufacturers have their own home pages on the Web with information and addresses.
