Adding a library shelf with books as a material

I want my model to like like a library with books on shelves. None of the patterns depict library books. I have the skeleton of the model depicting the library layout. I just want to make it more authentic by having books on the shelves.

You should be able to find some book components in the 3D Warehouse and you can always modify them once you have the components in your model. Or you could model them yourself. Or if you can find a photo of the sort of books you want, you could use the image as a texture on a face positioned on the bookshelf.
