*******THIS BOOKCASE IS NOT SOLID WOOD OR WHOLE WOOD.******

Delivery was 4 days earlier than initially identified at purchase. Instructions were not difficult to understand and provided direction throughout assembly. Finishes look great. Backing is 8 pieces of thin plywood held together with thin packing tape; it was not difficult to secure to the bookcase and make it look good. Bookcase is made of particle board with wood like veneers. All boards but the backing are particle board.
