Several persons were particularly helpful in the preparation of this book for publication as a paperback. John T. Hubbell, the director of the Kent State University Press, suggested the project and patiently waited for the revised manuscript. Michael B. Ballard, Charles D. Lowery, and William E. Parrish, all of Mississippi State University, offered their usual cogent criticisms. Susan Hall and Jackie Cloutman of the Interlibrary Loan Department, Mitchell Memorial Library, Mississippi State University, efficiently tracked down my many requests. Bridgette Neely, my student-assistant, deciphered my constant changes on the word-processed text and bibliography and somehow made sense of it all.
