Cataloging help?

OK, so do/how do you all separate fiction from comics?  My system is breaking down.  (We use Library of Congress for nonfiction, but that's terrible for fiction.)  I have a rough system of "nonsequential comics like Gorey or xkcd shelved with fiction, sequential shelved as comics."  But it's only rough and I'm not really sure I want Maus shelved alphabetically by title with the comics instead of alphabetically by author name with the fiction.

Any suggestions?  (To make matters worse, I shelve tie-in novels and scripts alphabetically by series title in with the fiction, except for screenplays by Robert Bolt.)  A pure mix is unlikely because of shelf height issues; I think it makes sense to have the noncollected comics, issue by floppy issue, segregated from regular fiction, though I could probably be argued into a change.
