The Humanoids

US original and the true first book edition; the census claim is correct. The text was first serialized in Astounding Science Fiction (1948) as "…And Searching Mind", a sequel to the 1947 Astounding novelette "With Folded Hands" — magazine appearances only, not book editions. The first British edition is Museum Press, London, 1953, four years after the US book, so the Simon & Schuster 1949 clearly holds precedence and the UK issue is not a rival first. New Mexico author (Portales); this is the trade-house counterpart to Williamson's Fantasy Press titles.
