ACKNOWLEDGMENTS

Many persons have helped in the preparation of this book. I am heavily indebted to Gregory Grossman, who suggested the cement industry as a fruitful case study for Soviet spatial analysis and who gave generously of his time and counsel. Robert Campbell’s substantive advice and editorial skill have greatly improved the presentation. Holland Hunter commented usefully on earlier versions of the study. Leon Moses, Benjamin Ward, and George Wilson also contributed helpful advice. Leon Herman assisted in locating information at the Library of Congress which I needed to revise the study while I was working in Brazil, and the resources of the Library had been invaluable earlier while I was doing the main research for the study in Washington. Edwin Haefele, Wilfred Owen, and Joseph Pechman provided a hospitable working environment at The Brookings Institution; their help, the generous financial assistance of that organization, and the support of the United States Agency for International Development, which sponsored the Brookings studies in the field of transportation and economic development, are all gratefully acknowledged. None of these organizations or persons necessarily shares the conclusions of the study, and any errors are solely my responsibility.

I would also like to thank the editors of Soviet Studies and Basil Blackwell, its publisher at the time, for permission to include here information originally contained in an article I published in that journal.

Finally, I want to thank Ann. Her aid, encouragement, and cheerful willingness to play the role of academic widow have always gone far beyond the obligations of the marriage vows.
