Note: The UK Science Fiction Adventures started out as reprints of the second US magazine called Science Fiction Adventures. The first five numbers of SFA (UK) were drawn from SFA (US 2)'s entire span, though the US magazine had folded by the time SFA #3 came out. From #6 onwards, SFA reprinted the odd story from other magazines but otherwise almost all of its content was original. SFA was the third magazine of the Nova Publications stable, along with New Worlds and Science Fantasy, and was edited by John Carnell throughout its life, though Larry Shaw was credited as joint editor on the first five numbers.
