US true first: Boston: Houghton Mifflin, 1971 (ISBN 0395127211). The first British edition followed from Oxford University Press, London, 1 June 1972 (ISBN 019211817X) — a distinct edition collected in its own right as the UK first, but not the true first. First thus trap: Houghton Mifflin's 2001 reissue under ISBN 0618083435 / 9780618083435 is a modern reprint despite carrying the same publisher imprint.
