1. How do you organize your books? By genre, by last name, by title, by publication date?
This is a little complicated. There are five bookcases in the apartment, plus the built-in shelves by my desk. Three bookcases are Chris's, and he organizes them; two and the built-ins are mine. One bookcase has four shelves of mixed YA and children's books and one shelf of general nonfiction. The other has four shelves of adult fiction and one of poetry and plays. Both bookcases are organized alphabetically by author last name, then by title (or series order, if it's a series), with the new acquisitions stacked on various shelves waiting to get places. The built-ins have my writing reference books: mythology, history, paranormal stuff, style guides, etc. These are organized by similarity (e.g., all the mythology together, grouped by cultural origin).
We also have several boxes of books that wouldn't fit on the shelves; these are organized by subject (kids fiction, adult fiction, nonfiction, my psychology texts, etc.).
2. Do you have a shelf reserved for your favorite books and/or authors?
Nope, they're mixed in there with the rest. But none of the favourites are in boxes, of course. :)
3. What is the first title and author on your bookshelf?
On the YA/children's bookcase, The Book of Three by Lloyd Alexander. On the adult bookcase, Flatland by Edwin A. Abbott. (Like I said, alphabetical.)
4. What is the last title and author on your bookshelf?
YA/childrens (or rather, the nonfiction on the bottom shelf): The Last Great American Hobo. Adult (plays and poetry on the bottom): e.e. cummings Selected Poems. (The bottom shelves are not very organized.)
5. What genre dominates your collection?
In both the YA/kids and the adult, speculative fiction (fantasy, science fiction, supernatural, horror, etc.).
6. Which author is the most represented? (You own the most number of books by . . . )
If we're counting each book in a series, then C.S. Lewis--I have all seven of Narnia plus The Screwtape Letters. If we're talking about unconnected books, it's a tie between Roald Dahl and Diana Wynne Jones.
7. You own all of the books written by . . .
No one, as far as I know. Even my favourite authors have written some books that aren't my thing, and I'm not much of a collector for collecting's sake.
8. You own the entire series of . . .
Chronicles of Narnia, The Time Quartet, and The Dark Is Rising (though I have only read one of the last set). Oh, and as nonfiction goes, The Masks of God (none of which I have read all the way through, but I will some day, dammit!).
