This is a well-constructed attractive bookcase. The directions are excellent but I would suggest that the "A" and "B" boards be clearly labeled top and bottom. If you don't use an electric drill, the tightening of the screws is a little tedious but not difficult.  Be sure to fully tighten. A second person is particularly helpful when you are affixing the top and bottom boards to the shelving.  I would rate the final product once assembled as an A and the assembling process a B+.
