Three publication dates for each book are given because, in the system developed by Pierre-Jules Hetzel for the Voyages Extraordinaires, each of Verne's novels was published successively in several different formats. This resulted in several distinct editions of each texts, as follows.[7]
Serial (known as éditions pré-originales, pre-original editions): Serialization in a periodical, usually Hetzel's own biweekly Magasin d'Éducation et de récréation ("Magazine of Education and Recreation", founded 1864). The serialized installments were illustrated by artists on Hetzel's staff, such as Édouard Riou, Léon Benett, and George Roux.
In-18 (éditions originales, original editions): complete unillustrated texts published in book form at in-18 (18mo) size. (Similar versions in the slightly larger 12mo size, with illustrations taken from the serialization, are also considered éditions originales.) This edition is almost always the first book-format printing; the one exception is Claudius Bombarnac, which was first published in a grand-in-8º edition.[8]
In-8 (cartonnages dorés et colorés, gilded and colored bindings): Complete editions of the text, published in grand in-8º ("large octavo") book form with a lavishly decorated cover. These deluxe editions, designed for Christmas and New Year's markets, include most or all of the illustrations from the serializations.
The posthumously published volumes in the Voyages Extraordinaires were extensively altered, and in some cases entirely written, by Verne's son Michel.[9]
