Hmm... I have a really old edition of the Encylcopaedia Britannica (1985 I think). Some books on programming (Visual Basica and C++), on another shelf I have a Grainger catalogue (like 700 pages thick or so), American Heritage Dictionary, another book on C++, book on American Folklore, "Further Predictions of Nostradamus" (found it on the floor outside infront of a dumpster), a copy of the Holy Bible (no, not religious or anything like that, but it's good to have a copy of it for reference), some mechanical books on old Ford vehicles, and some other crap. On another shelf we have a ton of our really old children's books. Finally, I have my own personal little library of books by the greatest author of all time: Robert A. Heinlein.
