I found the bookcases very easy to put together.  However, one of the bookcases was damaged at the top (the crown moulding on the ends were chipped) and missing some screws.  Fortunately for me, my brother is a carpenter and he was able to fix the problem for me.  I would have returned the damaged bookcase, but I was on a very strict timeline.

The other bookcase was perfect!  Thank you.
