But my motivation was more a matter of wanting to create order - to keep track of things. All those boxes full of photographs and sketches weigh you down, because they have something unfinished, incomplete, about them. So it's better to present the usable material in an orderly fashion and throw the other stuff away. That's how the Atlas came to be, and I exhibited it a few times.
