The UK edition, published by Atlas, appeared August 1939-August 1963. The contents were severely truncated during the 1940s, and the magazine did not appear regularly, adopting a variable bimonthly schedule. It became monthly from February 1952; from November 1953, when it changed from pulp to digest, it was practically a full reprint (four months behind in cover date) of the US edition, although some stories and departments were omitted.
