How do you organize your home libraries, nerdfighters?
I own many hundreds of books, all packed into my tiny room. My shelves don't leave much room for creativity, so I cannot use the celebrated 'color-gradient' organizing method. I've opted for a rough category system instead. Librarything.com helped me out a lot!
These are my current categories:
-fantasy / urban fantasy
-'real' literature (classics / modern classics)
-books about books/writing
-YA authors who are friends (John / Maureen / E. Lockhart / Scott Westerfeld / David Levithan, etc.)
Edit, November 2011: Hiya! It's been a while since this post, and since then my home library has changed. I've got fiction, YA, nonfiction, biography + memoir, drama, poetry, reference, and travel. This makes a bit more sense than the last system, I think!
If you're interested, I've got my whole library photographed and catalogued here. Enjoy!
I've got about 300 right now and they are essentially unorganized. :)
However, I do pose action figures in front of the gushy romance books in an effort to de-gushify them a little. So does that count as organization?
Shelf 1: my Hunger Games display because I loved those books so much.
Shelf 2: Other dystopian books, books based on mythology, historical fiction, and my 7th grade social studies textbook.
Shelf 3: More historical fiction, mystery, science fiction, fantasy, realistic fiction, and John Green books.
Shelf 4: Adventure/fantasy and more historical fiction.
Shelf 5: More realistic fiction, assorted other, and nonfiction.
I have three broad categories: Hardcover, Paperback and Textbooks/Yearbooks.
The yearbooks and hardcovers go together arranged by height.
Paperbacks start on the next shelf and take up the rest of my built-in bookcase also arranged by height - but also by author because those generally happen to be the same height (especially when they use the same publisher each time).
Textbook storage is more lax than the rest. Some are nicely placed in some crates serving as bookshelves and the others are in a pile in my rented room here at school (note: most of my books are at my parents' house)
Series of books must be in the same binding as the first one I buy of that series (Ex. I bought The Alchemist of the Secrets of the Immortal Nicholas Flamel series in hardcover, therefore the rest must also be in hardcover.) This rule is annoying when collecting paperbacks since books in the US always come out hardcover first and you have to wait at least a year for the paperback....
Well, on the first level of my shelf, there are the books who have black covers. (Twilight [13-year-old phase, plus, I can't actually throw them away, can I?], Vampire Diaries, Vampire Academy etc)
I have the trilogies/series on the second level: The Mortal Instruments, Divergent, The Hunger Games, Harry Potter, The Chronicles of Narnia and Lord of the Rings.
On the third level, I have books which are...um...shorter/standard novel sized. Eg. Jodi Picoult books, Southern Vampire series, Alice Sebold books, Nicholas Sparks books etc)
Fantasy novels are on the fourth level: Inkheart trilogy, The Inheritance Cycle series, His Dark Materials trilogy and Dianna Wynne Jones books.
On the last level, I have the classics like The Scarlet Letter, Jane Eyre, Wuthering Heights etc.
I used to have all my books organised by genre, author, and series. I moved house, and my entire family's books are either in bookshelves, but not organised beyond non-fiction or fiction, or in piles. I have books all over my desk, in piles on the floor, in shelves that weren't meant for them, on my bedside table, and on my bookshelf.
I'm going to organise them next summer. I will. I won't put it off. (Even if I'll probably forget.)
