During our 21 years of homeschooling, I always had the books organized according to subject. It was great to be able to know exactly where to go to look for a certain title. Once we decided to turn the schoolroom into an office at one end and a TV room at the other, many of the books had to be evicted. I quickly found new homes for them, but I still always picture them in their former locations. That makes it a real challenge to find a missing book!
Now they are only slightly organized, the Civil War books being in our bedroom (I just realized how funny that actually is, for my husband and I have had no battles for a very very long time!); theology books mostly at the stove end of the living room, although some are also upstairs at the end of the hall; old school readers mostly in the office; historical fiction and biography mostly in the TV room; cook books in the pantry; picture books under the window seat; reference books in the office; a couple Grosset & Dunlap collections in the TV room; various and sundry books scattered here and there, though slightly organized e.g. James Herriot books are together, P.G.Wodehouse books are together, etc.
Most of our books have come from used book stores, garage sales, library sales, and Amazon new-and-used. When I'm browsing a used book store (one of my favorite pastimes), I can't walk past a book whose spine is unreadable without picking it up to read the front cover or inside title page. I figure that a worn out book must be an often-read book, so it's worth picking up.
Many of the books pictured above are old British history textbooks, children's science books, or tales of heroes.
How about you? Do you also love used books? Can you get lost for hours among the stacks of a used book store? Do you brave the dust to get at the really good finds? Do you find yourself trying to read the titles of books in photos? like mine?? :-)
