OPUS was a British independent, which began as a monthly magazine by Ian Keable-Elliott, Chris Power (as illustrator), J.J. (Johnny Johnston, as promoter) and David Britland (as technical advisor on tricks.)
They accepted no advertising and wrote only about what they want to write about.
When Ian announced that he was quitting Opus, Chris and JJ continued, spurred on by Ian's belief that they wouldn't be able keep it going without him. After Volume 3 they hit readership figures that made the cost of production not too prohibitive and Opus fell behind with it's publishing schedule. There was only one issue in 1996.
In 2004, Vol.5, No. 11 appeared after a hiatus of four years and it was announced that the Vol.5, No. 12, would be their last. 
They also run a small magic convention in the UK once a year.
