The online presentation of The Wilbur and Orville Wright Papers at the Library of Congress, comprising about 10,121 library items or approximately 49,084 digital images, documents the lives of Wilbur and Orville Wright and highlights their pioneering work which led to the world's first powered, controlled and sustained flight. Included in the collection are correspondence, diaries and notebooks, scrapbooks, drawings, printed matter, and other documents, as well as the Wrights' collection of glass-plate photographic negatives. The Wright brothers' letters to aviation pioneer and mentor Octave Chanute, from the Octave Chanute Papers, were also selected for this online collection. The Wright Papers span the years 1881 to 1952 but largely cover 1900 to 1940. This online presentation includes the famous glass-plate negative of the "First Flight" at Kitty Hawk on December 17, 1903, as well as diaries and letters in which Wilbur and Orville Wright recount their work that led to that day.
