Billy Bookcases at IKEA

I am pleased.  I spent most of today (Sunday) installing a wall of new bookshelves that I purchased at IKEA.  These Billy bookcases are a fantastic bargain: at 79 inches (2.0 m) in height with six shelves apiece they provide ample space.  The four cost only $430 combined and provide sixty linear feet (18.3 m) of storage space, not counting the cabinet tops.  This means that there is actually some unfilled space!  I would love to post a picture, but I cannot find the serial cable for my digital camera.
