Take the book up to the third floor of the library .
把这本书送到图书馆三楼。
When I picked the book up it came apart in my hands .
我把书捡起来时，它就在我手上散开了。
An l-shaped wedge of metal holds your books up against the wall while a tiny clip holds the inside cover of the book up giving your larger books the illusion of magically sticking to the wall .
