Some books could easily fit in more than one genre. I've always found the literature section an odd one, because all good books are literature. And a lot of horror books are also science fiction or fantasy. And fantasy just means something fantastic or imagined, but it's turned into castles, magic, and dragons. Which means other fantasy books that don't include magic, dragons, and castles have to go elsewhere. And what about supernatural books? Yes, they could be horror, but they could also be fantasy or suspense.
I get annoyed for two reasons. First as a consumer I've had trouble finding a specific book I went into the store to buy, because I wasn't sure of the genre. Second, as an author I'm not always sure how to classify my books. My most recent title, Wandering Koala Digest 1, contains a supernatural thriller, but also a science fiction novella. So do I put it in horror, because it's not really horror, but there is no supernatural category? To me that's like putting a square peg in a round hole--it just doesn't fit so well.
That's one of the joys and wonders of the digital bookshelf--a title can be listed in multiple places without having to place a physical copy in each one. You can also search for a specific title and get right to it. It's no wonder I've gravitated more and more to buying books online and as digital editions even though I love the feel and smell of a physical book, and I love browsing bookstores.
So what does any of this have to do with the above illustration? It could easily fit in several categories: science fiction for the weird monster, pulp fiction for the protagonist, horror or supernatural for the weird monster, graphic novels for the visual nature, young adult because that's usually the reading level I write, or even holiday/special occasion for Halloween because of the weird monster. Maybe we just need a Weird Monster genre?
