Okay. So if I move my bed so it's flush against the wall, get rid of the nightstand, push the armoire-turned-bookshelf about six inches to the right, and take down the Phantom of the Opera poster on the wall (which I've been meaning to do anyway), I *think* I can fit one more bookshelf in here. By god, I will do it.
Looking at
Neil Gaiman's oh-my-god-look-at-those-shelves-I-just-jizzed-in-my-pants library has inspired me. No more boxes of books stacked to the ceiling because I don't have room for them! Maybe the stacks will only be waist-high now!
I wonder where the nearest IKEA-like store is...
