META: Superhero Dewey Decimal Classification

[Tom Russell]

In the various fictional universes we write for, superheroes are real,
living, breathing people and as such would be the subject of real
books that one could borrow from, say, a library.

The question is, how would a book on "Superheroing" itself be
classified?  An individual superhero might get a biography in the
biography section.  And very specific topics-- heroing in history,
relevant legal rulings, things like that-- would most likely be filed
in their specific sections.  But what about a general reference work,
an overview?  Is it science?  Is it crime/detection?

Where in the Jolt City Library, for example, would _you_ put
Superheroes For Dummies?
