7. In Ways of Seeing (London: British Broadcasting Corporation and Penguin Books, 1972), Peter Berger included three chapters that he described as visual or "pictorial ." "These purely pictorial essays," he wrote, " are intended to raise as many questions as the verbal essays. Sometimes in the pictorial essays no [written] information at all is given about the images reproduced because it seemed to us that such information might distract from the points being made." I have drawn much insight and inspiration from this example. I have also been influenced by the comparative photographic essay by Peter Menzel, Material World: A Global Family Portrait (San Francisco: Sierra Club Books, 1995). Also important to my thinking was the photographic essay by Marina McDougall titled "Banalities of Information" in James Brook and Iain A. Boal, eds. Resisting the Virtual Life: The Culture and Politics of Information (San Francisco: City Lights, 1995). William McNeill included a series of comparative photographic essays in his World History, (New York: Oxford University Press, 1979) that I believe are excellent models for the representation of historical information. Finally, see the interesting and thought-provoking collages in Tyler Volk's Metapatterns: Across Space, Time, and Mind (New York: Columbia University Press, 1995).
