It's a fairly standard design.
Crown moldings at the top, baseboard molding at thebottom, with a two-fluted columns on the right and left. I set the adjustable metal shelf supports in a dado to get full shelf width. The shelves are 3/4" plywood and have a bullnose applied tothe leading edge to give them strength and the look of a thicker shelf. Now I just have to fill it up with books.
