This book lays out a variety of opinions on regionalism, its history and its future. While the essays do not comprise a debate, pro and con, about regionalism, they do provide a wide array of perspectives, based on the authors' diverse backgrounds and experience. Some contributors have made close academic studies of how regional action occurs, in various states like Minnesota, California, and Oregon; others give an historical account of a particular region like that surrounding New York City; and yet others point out aspects of regionalism—race, especially— that should not be ignored. Why did past efforts at regional collaboration fall apart? What did regionalist efforts of decades ago leave undone, and what new goals should regionalists set? Without an understanding of these questions, policymakers and advocates may find themselves "reinventing the region." This book provides an important understanding of how regionalism has played out in the past, how policies shape places, and the possibilities and limits of regional action. Bruce J. Katz, director of the Brookings Institution Center on Urban and Metropolitan Policy, was formerly chief of staff at the U.S. Department of Housing and Urban Development.
