How we organize all the books

I LOVE getting questions from readers! This one came right after our new Library Bookcase post.
Thanks Jennifer!

I don't have an overly organized bookcase. By 'overly organized' I mean I don't have it organized alphabetically or by the Dewy Decimal system. 
I read mostly non-fiction so our fiction section fits on one shelf alone. As for the rest of my non-fiction collection I organize them by topic.
While I don't have a super organized system, I do have a weird system all of my own. Well the system itself isn't weird but the categories are a bit unorthodox. Here are the topics found in our library:
1) Healthy Living. Mostly heath books, or exercise books.
2) Sewing and other craft books.
3) Finance Books, I love a good finance book. I have no idea why but I love books about saving money. I think it's the organizer in me . . . I love new ideas on how to organize our spending.
4) Spiritual books. 
5) Biographies, every one from Tori Spelling to Sidney Poitier, my tastes vary greatly in this area.
6) Green Living, this section takes up two shelves. Here's one:

7) Gardening.
8) Simple Living. I have enough books on simple living to garner their own shelf. Ironic because having tons of books on the same subject is definitely NOT living simple ;).

9) Style books. Books on pretty clothes and defining your personal style. Choosing clothes and defining my own style wasn't something that came easily to me. I found a lot of help in the writing of people who have it together in that department!
10) Adoption books. This is also where we'll keep the books on babies and kids and subsequently teenagers.
11) An entire shelf dedicated to Home Organization. 
12) Another shelf dedicated to Home Design.
13) Cleaning and Home Maintenance. 
14) I have an entire shelf for Ms. Martha Stewart herself. I have no idea why I have a whole section on Martha. All of her books could fit into other categories in the bookcase but for some reason I like grouping them all together!
Last is my favorite section:
15) An entire shelf for "Housewife" Books. Those are books that have anything to do with being a housewife. Or any retro books about women.

And that's how we do it. I could alphabetize them within each category but so far I don't have enough books to make that worthwhile. Maybe one day when we have more books we'll need to get them in alphabetical order, but now it's easy enough to go to the section and find the book I'm looking for.

I almost forgot to mention that the books that are either currently in use or that I have recently purchased and haven't gotten around to reading yet, get put on top of the lower bookcase between the A and Z. Once they've been read they get put into their respective categories. This way I ensure that I don't overlook or forget about a book I intended on reading! 

Bonus:
I collect Martha Stewart Magazines I have approx 150 of them. They are relegated to the bottom shelves of the bookcase because they are very heavy.
I hold the magazines in magazine holders from Ikea and I group them by month. That way I can grab an entire month at a time. It's really handy for planning seasonal menus or for holiday ideas! Just grab a month and you have am abundance of ideas for each and every holiday!

I hope that answered your question Jennifer!
