Every time when I move, the BIGGEST problem is my books. I have lots of books and each of them is heavy. If you have 10 or more books like INTRODUCTION OF ALGORITHMS to move, I know you will or had already felt my pain. If you look at the design below, you probably will think the same as me: I wish my books can go.
