This children's imprint of HarperCollins
is the successor to Harper Trophy
, an imprint of Harper & Row (or Harper Junior Books) established in 1970 or soon after, in use to 1990 or soon after.
This imprint was established sometime after News Corp (Rupert Murdoch) created HarperCollins Publishers, in turn sometime after its 1987 acquisition of the US publisher Harper & Row and its 1989 or 1990 acquisition of the UK publisher Collins (William Collins Sons).
As a "publisher" at ISFDB, HarperCollins Children's Books
is another children's imprint of publisher HarperCollins (UK)
, which publishes books in the UK only. (Elsewhere "HarperCollins Children's Books" is also used collectively for the children's imprints of the international HarperCollins Publishers.)
