What are your categories?

I feel like there must already be a thread like this, but I can't seem to find it. And I figure people might have changed their categories anyway--I certainly have!

Basically, I've fallen behind in reading these threads and can't decide where to start just based on a name. So, I'm wondering what categories people are doing?

Mine are:
8 Dewey Decimal Challenge
8 Ancient World
8 Math/Science
8 Children's/YA Fiction
8 Adult Fiction
8 LT Group Reads
8 Already-Started
8 Random

8 Debut Works
8 Learning About Other Cultures Books
8 BookCrossing Books
8 Books by Israeli Authors
8 Books Originally Written in a Language Other than English
8 New-To-Me Authors
8 Fiction Works about Teens or Young Adults
8 Short Stores or Essays

Ahem...These categories are still subject to change! :D

I've been pretty good about not changing my categories, though I sure have moved the books around on them quite a bit:

8 Gothic classics
8 Short story collecitons
8 Long books (500+ pages)
8 Books in Spanish
8 General Nonfiction
8 Literary Criticism or Author Biography
8 Sci-Fi/Fantasy/Horror
8 Longtime TBR

I'm very happy with the categories that I selected:

1. The oldest books in my closet
2. Canadian Lit
3. 1001 Books You Must Read . . .
4. Books for University
5. World Lit
6. Big Books
7. Book Club
8. Other books from my closet

The only category that hasn't worked out is my book club, either because we ended up skipping some months, or because I had already read the book chosen and didn't reread it. In other words, it was out of my hands. But I think I'll use some of the group reads I'm doing here at LT to fill this category.

Next year I'm going to add:
1. Women authors (with a focus on Jane Austen, Virginia Woolf and Margaret Atwood)
2. Prize winners

I'm not sure which two categories I'll replace them with.

My eight categories are:

1. 1001 Books
2. From the TBR Pile
3. British Classics
4. Books Released in 2008
5. Austen Addiction
6. YA Novels
7. Historical Fiction
8. Non-fiction

From the TBR pile started as a Shakespeare category, and Austen Addiction started as "Books by Authors who are New to Me." I'm thinking of dumping the Non-fiction category for a re-reads category, since I just finished re-reading three books, and am thinking of re-reading several others. Since my progress has been really slow otherwise, I might need to do that in order to make it to 64 books.

Biography/Memoir
I’ve Started and Want to Finish...

Children's/YA
Nonfiction
Short Stories

Discovered on LibraryThing!

My categories have stayed the same but I’ve swapped some titles.

Awhile back, Morphidae compiled the Top 10 categories.

I made mine an 8811 challenge, or something...
8 books in my TBR pile
8 books in history
8 books in Social science
8 books in Religion and Philosophy
8 books in Education
8 books in Language and Literature
8 books in Fiction (American Authors)
8 books in Fiction (non-American Authors)
8 Books in Science and Medicine
8 Books in Memiors/Humor
8 Books read for work

I may yet change these (I've already added one), but this is what I've currently got.

1. Non-European/American
2. Books that changed the world
3. Someone else's favorite book
4. Books older than dirt
5. Books in Japanese
6. Poetry collections
7. Folklore/Mythology
8. Just 'cause I want to!
9. Historic Nonfiction

I'll probably combine Folklore and Older than Dirt- they're too similar.

I finally am happy with these 8 categories. It was a tough decision, but these seem to bee the categories that a lot of stuff in my TBR pile is labeled.

1. Biography/Autobiography/Memoir

2. Horror

3. Non-fiction dealing with UFOs, abduction cases, etc.

4. Christian Literature

5. Books by Janet Evanovich

6. West Virginia History

7. Psychology

8. "Classics"

My completed 888 Categories are:

8 Victorian-Era Novels
8 French Language Novels
8 Philosophical Works
8 Nobel Laureates
8 Contemporary Authors
8 Books by Women
8 Playwrights
Short Stories by 8 Authors

I also have eight extra credit categories:

1001 Books You Must Read Before You Die
Spies and Private Eyes
Literary Traveler
Speculative Fiction
Dystopia
The West
(Semi) Autobiographical Novels
Non-Fiction

My categories, with 8 books in each:

1. Poetry
2. Science & Natural History
3. History/Biography/Politics
4. Fiction by authors whose other work I've enjoyed
5. Fiction by authors new to me
6. Comic collections/graphic novels
7. Personal development
8. Science fiction & fantasy

I don't expect to finish them all this year, but it's good to have a plan!
