I have a wall behind a couch and would like to mount book shelves on it above the couch. The wall is made of thick wood panelling. The area for the shelving is approximately 4HX10W.

I would like to mount the shelves with no visible means of support (no brackets) although due to the length of the shelves I probably would have to have some verticle supports/dividers betwen the shelves to prevent bowing.

Is there a technique for doing this?

Thanks
