I would like to thank John Lee, Malcolm McKinnon, Arthur Rubinoff, Julian Tanner, and Morton Weinfeld for their informative feedback on all or part of the manuscript. Several anonymous reviewers also made significant contributions to the work. A special thanks should be given to the staff at the Bladen Library, most particularly Elizabeth Seres, for their helpful support. Recognition should also go to Frank Austin for his editorial assistance in the preparation of the book. Finally, I would like to thank my wife, Bev, for affording me the opportunity to write the book and encouraging me in the effort. She also scrutinized the manuscript to make sure that it remained clear and readable. For all their efforts, I remain fully responsible for the text as it appears.
