The Gods of Mars

US original — the McClurg Chicago 1918 edition precedes all others and is the true first in book form. The first UK edition is separately collected and should be named: Methuen & Co., London, 1920, with 'First published in Great Britain in 1920' stated on the copyright page, in green cloth lettered black. The text first appeared serially in All-Story, January–May 1913, so the 1918 McClurg is the first book appearance, not the first publication of the text.
