The Boys from Brazil

The census claim is confirmed: US Random House (New York) is the true first. It was published March 8, 1976 per Kirkus and reviewed in The New York Times 'Books of The Times' column on March 10, 1976; the UK first from Michael Joseph (London) followed in April 1976 and is separately collected in Britain. Michael Joseph firsts of the period are identified by a 'First published in Great Britain (month, year)' statement on the copyright page, with subsequent printings noted (Quill & Brush). Caution: the Wikipedia infobox gives '21 October 1976' for the Random House edition, which contradicts both the Kirkus release date and the March 1976 NYT review and should not be relied on. First-thus traps: the 1978 film tie-in issue and the later Pegasus Crime Classics reprint.
