Throughout Guy's book (except the cover), it is spelled "Common Lisp" rather than "Common LISP" or "COMMON LISP", so that sets the precedent, I think. No reason to change. Guy does use a funny font whenever he says "Common Lisp", but that doesn't change things. I think that McCarthy's LISP 1.5 was all uppercase, I think, but that's because capital letters were easier to carve on stone tablets. -- Scott
