I am so pleased with this purchase.  It arrived on schedule, the contents of the box were in good condition (considering the bookcase was made in Taiwan, so it traveled far and wide), and although it was left on my front porch, I was able to get it inside with some good old fashioned elbow grease (the box was over 100 lbs.).  I had printed out the instructions when I submitted my order so I had a few days to read over how to put the bookcase together prior to delivery.  It took me about three hours and I had to use pliers and a rag to wrap around the allen wrench because it could only turn the screws so far, but that was the only difficulty.  Once done, it was easy to stand it up and push it against the wall.  It looks great!
