How do you store/organize your LO's books? (I always love pics ) Do you like your system?

Right now we have L's books on a shelf under a dresser in her room. It works well to store them, but it is not useful for her to get them out and put them back. They fall out the back/off the sides, and there isn't a ton of space between the shelf and the dresser, so it's difficult for her to put them away without getting frustrated.

I like the idea of those spice racks turned book storage, but wonder how functional they are, or if they're just for looks?
