Paul Collins writes: “On November 22, 1820, the New York Evening Post ran a perfunctory book ad that was none too particular in its typesetting: ‘WILEY & HALSTED, No. 3 Wall Street, have just received SYMZONIA, or a voyage to the internal world, by capt. Adam Seaborn. Price $1.’ As literary landmarks go, it’s not quite Emerson greeting Whitman at the start of a great career. But this humble advert may herald the first American science fiction novel.”
