Well, I can see: "The C?????? Oxford English Dictionary", bellow the clock. "Graph Theory", just behind the humidifier thingy.

A pity the resolution is not better.

Ya, also there is Cormen's book & Unicode 1.0 (I guess--not sure) :)

That's Unicode 3.0 if you are referring to the shelf on the left, above the stereo.

The Complete Oxford English Dictionary.

Compact Oxford English Dictionary, I think.

Just above the paper he's reading I think - System Progamming by John Donovon.

Knuth's own TeX series (TeXbook, Metafont book, etc) is on one of the shelves.

Also: what is that painting on the wall?

I also cannot figure that out but it seems amazing, too. Anyone, knows what this is (and artists' name)?

dollars-to-donuts its an Ed (Edward) Ruscha. I've got a book filled with his word-phrase images.

Ahhh... I was referring to the painting on the left, the image of the library. Methinks you were referring to the painting on the right?

Book name ?

They Called Her Styrene: http://www.amazon.com/gp/product/0714840114

Yes, the print on the right; no idea about the print on the left.
