The Thirty-Nine Steps
John Buchan · William Blackwood and Sons (Edinburgh and London) · 1915
True first is the UK Blackwood edition, published October 1915. The first American edition (George H. Doran Company, New York, title page dated 1915) was registered for copyright on 30 October 1915 but publisher records indicate it was probably not issued until early 1916; both are collected, with the Blackwood edition holding clear precedence.
