I LOVED this post! Someone else with zillions of books! One time I estimated I had about 5000 books in this house! A LOT of them were for homeschooling and now live in the attic.

My office has classics only. The hall bookcase has non-fiction: plants, health, how to do, herbals, cat, and misc. There's 1.5 bookcases with National Geographics going back to 1916. Two stairwell bookcases of thrillers/mysteries.

One bedroom is all horse books, fiction and non-fiction. One bedroom has 3 bookcases and the top of the bureau of all kinds of books, 2 shelves of James Michener.

And this is the living room big bookcase. There's a smaller one on the other side of the room.

I've written a post, will put it up tomorrow, about my bookcases and books.
