Wilbur and Orville Wright took more than 300 glass-plate photographs of their expeditions and later travels. These negatives were donated to the Library of Congress. Many were damaged when Dayton, Ohio was flooded in 1913. The microfiche publication, available in many libraries, is entitled: Photographs by the Wright Brothers.
