There is more to Jules Verne's famous book about traveling into the Earth than I thought! This is what I learned when I went back to the second issue of Amazing Stories and saw the first part serialized there.
The original was published in French in 1864, then re-published in an expanded version in 1867. Then, the first English version was released in 1871, but here's the kicker: that first English version was drastically altered from what a straightforward translation would have been! The character names were changed, which may have been forgivable, but the structure of the story was actually pretty different, too. That "localized" English version was Journey to the Centre of the Earth.
