In this major new work of urban geography, Allan Pred interprets the process by which major cities grew and the entire city-system of the United States developed during the antebellum decades. The book focuses on the availability and distribution of crucial economic information. For as cities developed, this information helped determine the new urban areas in which business opportunities could be exploited and productive innovations implemented.

Pred places this original approach to urbanization in the context of earlier, more conventional studies, and he supports his view by a wealth of evidence regarding the flow of commodities between major cities. He also draws on an analysis of newspaper circulation, postal services, business travel, and telegraph usage. Pred's book goes far beyond the usual “biographies” of individual cities or the specialized studies of urban life. It offers a large and fascinating view of the way an entire city-system was put together and made to function. Indeed, by providing the first full account of these two decades of American urbanization, Pred has supplied a vital and hitherto missing link in the history of the United States.

This book analyzes how information circulated before the telegraph. Using newspapers and their contents, postal services, the volume of commodity trade, and travel patterns to analyze information circulation, Allan Pred provides a cogent and complete description of interrelationships among the large cities during the period from 1790 to 1840. His principal concern, however, is with general urban-growth and locational processes. Developments between 1790 and 1840 are studied in order to understand the growth process of all systems of cities, both past and present.

Allan Pred has developed a multiple-loop feedback model to describe the process by which a few cities established their long-term dominance, or high rank, during the early growth of particular urban systems and subsystems. The model includes non-local multiplier effects generated by local urban growth, allows interurban trade and information flows mutually to reinforce one another, and permits “spatially biased” information circulation to influence where business opportunities are exploited and how economic innovations are diffused. Several interurban innovation diffusion processes are examined to confirm the validity of certain aspects of the model.

Examples of both hierarchical and non-hierarchical diffusion processes are given, including the spread of the Bank Panic of 1837, daily newspapers, and steam engines. Much information is presented in the form of clear and illuminating tables, figures, and maps. This study, by historical perspective on social change and deeper insight into the importance of information circulation in urban growth, should be immensely valuable to current regional and locational planning.
