Confusingly, Amazon.co.uk lists this as published by Pergamon Press (in August 1978), while Amazon.com says it is published by Maxwell Macmillan (June 1978). Presumably not the U.S. branch… they share an ISBN, though given how those work for English-language works it's impossible to tell whether it is from the U.S. or the UK.
Of course, anyone can write descriptions. There's a review mentioning a paperback from Futura (unreferenced Wikipedia article) with an entirely different cover; I believe that was also a UK publisher. The review says 1978, Amazon says 1984.
