Man and Superman: A Comedy and a Philosophy

The London/Westminster edition (Archibald Constable & Co., 1903) is the true first; both editions are collected. The first American edition was published by Brentano's, New York, in May 1904 and follows the English edition by roughly nine months, so no US precedence trap exists here — the census claim is correct as stated. Later Constable collected-set appearances (Standard Edition and subsequent series) are first-thus reprints, not the first edition.
