This collection originated from extensive research on seven U.S. cities: Berkeley, Boston, Burlington, Chicago, Cleveland, Hartford and Santa Monica--all largely from the 1970s and 1980s. Over time we learned about, and there occurred, broadly similar experience in other places, and as material came in, we have begun to add these to the collection: from Asia, Africa, Europe and Latin America; and from other cities in the United States. Our collection being limited in these latter places, we have aggregated them by continent. All these are presented along with a set of introductory texts.
