Outside the Main Series
Paris in the Twentieth Century & The Lighthouse at the End of the World: F
(Both of these, while not strictly in the series, are near-misses; Verne intended Paris to be one of the Voyages, but it was declined by the publisher, and Lighthouse was intended for the series and almost finished, although it was published posthumously with some slight editing by Verne's son.)
