Consider this as a first draft of a history of seventies science fiction. I'm sure there are omissions, but at the moment I'm more worried about covering central texts than marginal. I suspect this is UK-centric and is lacking in Australian, Canadian and New Zealand..ian authors. I'll dip into Strange Constellations and Canadian Science Fiction and Fantasy
