Do we really know how much Star Trek there actually is. The category doesn't tell you that much, because it's all split into these stupid subcategories and subsubcategories and so on in an infinite recursive loop.
E.g. you can go into Star Trek books http://en.wikipedia.org/wiki/Category:Star_Trek_books but then there is a whole load of stuff underneath that. There is also another separate category of novels http://en.wikipedia.org/wiki/Category:Star_Trek_novels, which also descends into other things that may or may not include the main category. There is also a list of Star Trek lists http://en.wikipedia.org/wiki/Category:Star_Trek_lists .
List of Star Trek planets http://en.wikipedia.org/wiki/List_of_Star_...s_(A%E2%80%93B) - and this is just A-B.
How much actually is there?
