Speaking of which, on the left side, lower unit, just below the middle
shelf and just below the third from bottom shelf the back appears to be
lit up. Is there a opening at the back of the shelves to let light
shine through or is that just a reflection off the books that are laying
down?

Reflection. It was dusk and I had all kinds of lamps on to get some
light in there.

Speaking of lighting up cabinets and other things, Lee Valley Tools
has just started marketing a line of LED tape lighting.
