New York: Viking 1978, first U.S. printing, hardbound in dust jacket. First published as Oeuvre Croisée in French (Paris: Flammarion 1976). A collaboration between Burroughs and Brion Gysin. Burroughs, known to have worked more productively in collaboration with others, wrote that the title stemmed from Think and Grow Rich, a twentieth-century guide to salesmanship by Napoleon Hill, who counseled that when two minds work together there is always a third one that results. Others have interpreted the third mind as coming from the interaction of writing and visual art.
