Cities Around the WorldThis site "presents over 6,100 photographic images from the slide collections of the American Geographical Society Library. The images selected for this project focus on architecture, city life, people, transportation and other aspects of urban development, such as neighborhoods, commercial streets, and business districts. The pictures were taken by two photographers, Harrison Forman and Harold Mayer between 1942 and 1994. The digital collection provides access to photographs of over 450 cities worldwide. In addition to present-day metropolitan areas, this collection also features ancient cities and deserted settlements, including Carthage, Great Zimbabwe, Machupicchu, and Persepolis." The images may be copied by individuals or libraries for personal use, research, teaching or any "fair use" as defined by copyright law.
