About Harlequin

Harlequin is a Canadian publisher of mass-market romance paperbacks, founded in Winnipeg in 1949 and now a division of HarperCollins.

Richard Bonnycastle, Jack Palmer and Doug Weld set the company up to buy reprint rights to existing novels and sell them as cheap paperbacks, partly to keep a printing works busy. The first title was Nancy Bruff's The Manatee (May 1949). The early list mixed westerns, mysteries, romance and non-fiction, mostly reprints of Agatha Christie, Arthur Conan Doyle, Somerset Maugham and James Hadley Chase, and its early best-seller was Jean Plaidy's Beyond the Blue Mountain.

In 1957 Harlequin took the North American rights to Mills & Boon's romances, and by 1964 it was publishing only Mills & Boon novels under its own name. It bought Mills & Boon outright on 1 October 1971. Harlequin Presents followed in 1973, and in 1975 the firm bought its first novel by an American author, Janet Dailey.

Torstar took a majority stake in late 1975 and full ownership in 1981. Harlequin bought its American rival Silhouette in 1984, launched the MIRA imprint for single-title novels in 1994, and was sold to News Corp in 2014, since when it has sat within HarperCollins.

Identification

How to identify Harlequin first editions

What to look for

The single most useful fact: Harlequin began as a paperback reprint house. For almost all of its first two decades, a Harlequin copy is a later reissue of a text first published by someone else.

1940s to 1950s

  • The early list was built on reprint rights to novels already published elsewhere, including Agatha Christie and Arthur Conan Doyle. A Harlequin Christie or Doyle is an early Canadian paperback, collected as such, not a first edition of the text.
  • First printings of early Harlequins are collected in their own right: the University of Alberta holds more than 500 first-edition Harlequins from 1949 to 1980.

1950s to 1960s

  • From 1957 Harlequin reprinted Mills & Boon romances for North America, and within a few years they made up most of its list. For these titles the London Mills & Boon edition came first; the Harlequin paperback is the North American issue.

From 1970

  • Where a book carries a number line, the lowest number present gives the printing; a line that includes 1 marks a first printing.
