It should come as no surprise that one of the most therapeutic and relaxing things for me to do is play with books. Rearranging, stacking, moving, fondling... It's one of the best parts of moving (because there aren't many great things about packing all your stuff into boxes, carting them up and down stairs, and then unpacking it all, only to have everything now dirty from being in boxes).
With the last move, once everything else was put away, I pulled all my books out of their boxes and stacked them around me in the middle of the dining room/library to try to make sense of how they had previously fit on the shelves. I've got a great picture of me somewhere sitting happily in the middle of a sea of books.
When we got new bookcases (a couple of years ago) I got to go through the whole process again. But today I finally got around to saving the Robert Jordans. With the addition of two new bookcases, it meant that they had to be squeezed in beside the one in the front room along a wall that gets direct sun in the winter. So ever winter, I have to leave the blinds half closed so the spines of my preciouses don't fade. This year, I've had a very ugly system of things propped up closer to the books to block the sun, because I need sunlight and having the blinds half closed just wasn't cutting it.
I just finished rearranging the books on three different bookcases to move the Jordans (and other fantasy books) to the dining room, far away from direct sun, and I moved books I don't care so much about (cookbooks) to the previous Jordan shelves.
In the process, somehow I came up with two empty shelves! They're in the front room, in the direct-sun area, so I can't fill them with new books or fantasy books. I'm at a loss with what to do with that space, but I'm very happy to have all my beloved books safe from the sun.
