I agree. Verne is best known as an SF author, and yet most of his books are not SF at all, but "travel adventures", such as this one!
I intend to post all the Verne that's available on PG, although that's certainly not all that he wrote - I would guess that fewer than half his books are currently available on PG. Perhaps many of them were never translated into English?
Currently proofreading The Poison Belt, by Sir Arthur Conan Doyle.
