I certainly love the turn this conversation has gone!
My frustration with how bookstores organize their shelves stems from the fact that i enter the store with
a list. And that list is most easily sorted alphabetically by author or title or both. Genre sorting is great (maybe) for this "browsing" thing people talk about; but genre sorting is also so arbitrary that I KNOW I have been in a bookstore that had a book on my list; but since they put it into historical fiction or literary fiction or whatever means I never saw the darn thing. Like now I know to look in literary fiction for Jonathan Carroll books. But in my ideal world, I would find the Jonathan Carroll books close to the PC Cast romance-urban-fantasy novels, and not so far away from Ramsey Campbell, John Dickson Carr, and Jack Chalker. That's the other thing. I like a lot of different genres of fiction. For me, I'm game to "browse" it all, cause I like it all, at least in theory.
Final point today on this - really, the internet is made for my kind of shopping. I've got a list, just look it up on Amazon or Abe or Thrift or whatever. Spend my shekels or dinar, go on my way. But some of the books on my list I wouldn't pay more than $1 used for - most books published before 1980 for example, so that when it inevitably disappoints me for it's -isms, it won't hurt to recycle. And really, the purpose of my list is to have some boundaries around my book buying. And by boundaries, I mean my list is ~500 books long. And my to-read shelf of dead tree books is also roughly 300 books (and graphic novels and RPG books). It's all about the hunt, at the end of the day. And AMZ, ABE, etc don't provide any excitement in the hunt. And I also like to support local business, wherever I may be.
Would you put graphic novels go with the rest of fiction or in their own section?
It's so hilarious to me that "graphic novels" in Dewey decimal system in many public libraries are slotted into non-fiction over in the 741.59 area (great
comic discussing the issue of graphic novels in Dewey. Note it's a pdf, so takes a bit of time to load, and may be terrible read on a phone).
For my imaginary bookstore that is good only for me (as I said upthread there) I would put graphic novels in their own section (same with RPGS, in a different section); but within the graphic novels section I'd alphabetize strictly by title. Again, Genre be damned as a fool's game. Conveniently, most superhero books start with the name of the superhero/supergroup in the title: "X Men Age of Apocalypse" "Batman Killing Joke". Maaaaybe the only exception I might make is for two things: Manga/Manhwa might be separate; and adult (as in p0@rn, not as it the same word meant in prose book publishing field) in it's own section. Which is good, as I have no adult graphic novels on my list so will make my searching much easier.
You're 100% right, you didn't ask about how I would organize my RPGs, but I'll tell you anyway

. Strictly by brand in alphabetical order. In other words Dungeons & Dragons would be on the shelf near Dungeon World. World of Darkness near to World of Dungeons. Within system, Core books first, then all other books by title. "What about third party publishers?""What about system agnostic adventures?" "what about this, or that, or even the other thing?" I will answer future questions once someone gives me ~$200,000 to start my own bookstore, and it actually becomes relevant
