R.U.R. (Rossum's Universal Robots)

The Czech Aventinum 1920 printing is the true first and is the book that introduced the word 'robot'. The first edition in English is Paul Selver's translation, published in 1923 in two distinct and textually different forms, both of which are collected: Oxford University Press (Humphrey Milford), London — Nigel Playfair's stage adaptation, small octavo in original printed black wrappers, pp. [1-5] 6-102 [103 ads] [104 blank]; and Doubleday, Page, Garden City, New York — the Theatre Guild version, reflecting the alterations made for the American production that opened at the Garrick Theatre in October 1922, with four illustrations from production photographs. The sources consulted do not establish which of the two appeared first within 1923, so neither should be described as 'the' first English edition without qualification; name the publisher.
