These look really great hung up, especially with our books on them. (We ordered 2 to use as a mini library in our nursery.) BUT they were such a pain to hang STRAIGHT!! The hangers on the back of the shelves themselves are not aligned evenly, so any type of level/ measuring won't really help you. It took us forever and 4 extra nail holes to get these straight, but once you do, they look really good. They hold a lot too in my opinion. Ours are already stocked full of books. :)
