At a glance, these bookshelves may seem like a simplistic model, however each piece of wood is realistically beveled & individually UV mapped. The same care has been taken for each of the books on the shelves which include UV maps of their own.
This may seem like overkill, but you may find the need to customize book textures or remove some books from the shelf. Additionally, you may find value in using the books out of context as individual elements.
Photoshop format textures are included as an accompanying file download and include layers and the book's UV mesh as a hidden layer. Customizing the textures should be quite painless.
The Cinema 4D, VRML, Collada(DAE) and Maya files all have correct pivot points for each book, and materials are kept intact. The OBJ file on the other hand, does retain model to material relationships, but the actual image files will need to be reloaded individually.
