Collecting information on interstate cooperation was a major task because of the relative lack of published current information. Numerous state and federal government officers, compact administrators, associations of state administrators, and individuals supplied information in response to my requests. In addition, a significant number of state government officers, compact officers, and association officers granted interviews to the author and/ or his research associates, and provided copies of materials that otherwise would have been unobtainable. The cooperation of these officers is reflective of their professionalism and their desires to improve the functioning of the federal system.
A special debt of gratitude is owed to colleague Stephen L. Wasby for critical comments on a draft of Chapter 6; research associates Brian R. Haak, Christopher W. LaBarge, Michael A. Landsman, Christopher P. Latimer, and Nicholas J. Parrella; Addie Napolitano for excellence in preparing the manuscript; and Robert Holm for editing the manuscript. Any errors of fact or misinterpretations, of course, are solely my responsibility.
