well, mine aren't perfectly arranged but I try to keep series together and authors together. xD And I have a hard over section and paper back.
But yeah, I have a list of books missing right now that I can't find so I will just have to rebuy them.(these are some of my favorite of the books I own)
I really love to read. Which is kind of funny because I did not learn to read until I was in the third grade and refused to read until I went to my first magnet school where reading was a major requirement and I learned how to judge my books. xD
