You and I sound like two peas in a pod! I am always going to the library's used book store and stocking up on books. I have a whole section in my book shelf devoted to books that I've bought but haven't read yet. Some have been there for a few years. I don't know what it is about old used books but I like them better than new ones.
I used to have a bunch in the bookcase. Now there all in Rubbermaid bins, in a closet under the steps, in the basement. My wife really doesn't wish to see them. Of course, this actually makes it easier to sneak more *in*.
