Catagories in my Personal Library

I decided to reorganize my books today. Before it was just a vaguely genre-based, vaguely sized-based system but now I have it organized by different categories. Of the categories, which do you enjoy most, in general?

General Fiction: Fictitious narratives, based in realism, that don't fall into any of the other categories like John Green's Paper Towns and JD Salinger's The Catcher in the Rye.
Mystery: Mystery books like Sir Arthur Conan Doyle's The Hounds of Baskerville and The Return of Sherlock Holmes.
Children's: Books written for younger kids like Roald Dahl's Matilda and E B White's Stuart Little.
General/Low Fantasy: Books that have unrealistic and fantastical settings and events but not in the style of, say, The Lord of the Rings and stuff like that, like Ayn Rand's Anthem and Charles Dickens' A Christmas Carol.
High Fantasy: Fantasy books with Tolkien-esque elements like magic, elves, dwarves, etc, like Rose Estes' Dungeon of Dread and Ursala K LeGuin's Tales of Earthsea.
Sci-Fi: Science fiction books like George Orwell's 1984 and Jeff Sutton's First to the Moon.
(Auto-)Biography/Memoir: Books about real peoples' lives, excluding musicians and people in the music business, like Anne Frank's Diary of a Young Girl.
Gaming Magazines: My small collection of magazines about video games, like Retro Gamer.
Harry Potter: Gets it's own section because it was more convenient, shelf-space-wise, than to put it with High Fantasy.
Comics and Manga; Sci-Fi: Sci-fi comics and manga like Star Wars and Sgt.Frog.
Comics and Manga; General: Fairly realistic comics and manga that don't fit into another genre like Charles M Schultz's Peanuts and Kazuo Koike's Lone Wolf and Cub.
Comics and Manga; General/Low Fantasy: Comics and manga based in non-Tolkien-esque fantasy like Rumiko Takahashi's InuYasha and Bill Waterson's Calvin and Hobbes (it cold be argued that C&H is fairly realistic considering most of the fantastical elements are imaginary, in fact, from that point of view it's more realistic than Peanuts, but it's more convenient, shelf-space-wise, so I digress).
Picture Books: Books, mostly made for kids, generally using more pictures than sentences, like Crockett Johnson's Harold and the Purple Crayon.
Activity Books: Books where you interact or play games like Kazunori Aihara's Let's Find Pokemon!
Music: Books about music and/or musicians/bands/people in the music industry, like The Beatles' Anthology and Martin Popoff's Contents Under Pressure.
Misc Big Books: Mostly year books.
Poetry: Collections of poetry like Sted Mays' A Kitten a Week.
General Non-Fiction: Real life books like Alex Boese's Elephants on Acid and Paul Parsons' The Science of Dr.Who.

Sounds like an interesting series. Definitely sounds like it fits in General Comics.
Personally I don't read as much as I'd like to, in fact I've started making myself read at least one chapter of a book each day. I want to become a bit more well read.

General fiction cause I'm as basic as sodium hydroxide 

I didn't read long enough to see that general fiction didn't include fantasy and sci-fi, which I prefer.

low fantasy i guess

Lately I'm into Terry Pratchett, Christopher Moore and Carl Hiaasen.  So.... humorous fiction?

also Harry Potter fals under urban fantasy subgernre.
