Probably not a particularly original question, but I’m not a huge cataloging person so maybe someone can answer this: why are all graphic novels cataloged together under nonfiction, instead of fictional graphic novels being filed with fiction and nonfictional graphic novels being filed under the relevant call number? Is there any other group of books that are lumped together based solely on medium/style instead of subject? I guess you could say that poetry and theater books are, but somehow it seems more appropriate in those cases.
