Lovely bookcases..I ordered two.  Unfortunately I am not happy that I discovered the stated measurements are deceptive.  Although the width is listed as being 39.38", in reality they are 35 1/2", which is almost a 4 inch difference.  Apparently the 39.38" refers to the topper.  As a result there is now an 8" space on my wall which is not covered by the two bookcases...a significant difference which I am not at all pleased about.
