The Colour of Magic

Precedence is genuinely tangled. St. Martin's Press in New York printed the sheets and released the US issue first (commonly cited as 21 October 1983); the Colin Smythe UK issue followed on 24 November 1983 after the jacket-blurb correction. Simultaneous publication had been intended. The Smythe UK issue (about 506 copies) is the publisher of record for the first Discworld novel and is far scarcer and more sought-after, but it is not unambiguously earlier by date than the larger US issue — collectors nonetheless treat the Smythe issue as the true first. The parallel US St. Martin's issue is documented on the-color-of-magic page.
