Not difficult to construct, tall & narrow which is what I was looking for, Makes a good "shoecase" since the shelves are closer together than usual in a bookcase.  BUT for some reason, the top end of the side panels is not finished.  It's tall enough that it doesn't show where I have it, but it wouldn't work if you had it somewhere where it could be viewed from above.  I'm hoping I can touch it up with paint.
