== New material on the relation to science fiction and science fantasy == 

 This article did not reflect the significant advances in SF critical theory made since the mid-1990s.  These advances (which I have tried to capture in a major rewrite of the science fiction Scope section) have implications for the discussion of fantasy.   

 I have added two paragraphs to the introduction that call out technology-of-magic and science fantasy as boundary subgenres that clarify the relationship between fantasy and SF.
