Horns

The US William Morrow hardcover (New York, February 2010) is the true first and is what dealer catalogues uniformly treat as the first edition. The census claim of a simultaneous UK issue is REFUTED by the dates found: the Gollancz (London) hardcover, ISBN 0575079169 / 9780575079168, is dated 16 March 2010 — roughly a month after Morrow — so it follows rather than accompanies the US issue. The Gollancz hardcover is nonetheless collected as the first UK edition; its copyright page carries a number line containing 1 (reported by one dealer as 1357108642, by another as "the numbers 1-10 present"). Both the Morrow and the Gollancz hardcovers are collected; the Morrow has precedence.
