The completion of this collection took many months, and, for a variety of reason, required the assistance and/or indulgence of a number of individuals. First and foremost, I would like to thank Tim Hudson for his useful input and support at the outset of the project Likewise, I would like to thank Jesse O. McKee for providing a hospitable environment during my affiliation with the University of Southern Mississippi. At Louisiana State University I am grateful to Sam Hilliard and Carville Earle for their invaluable understanding. The book became part of the GeoJoumal Library as a result of Wolf Tietze's confidence in the topic, and because of Henri G. van Dorssen's (and Kluwer Academic Publishers') good nab.lre - despite numerous 'problems'. Curtis C. Roseman, and the remainder of the Geography Department at the University of Southern California (where I completed many last minute details for the volume), are to be thanked for the cordial and warm environ ment I received while a visitor in Los Angeles. Finally, no multi-authored collection reaches completion without the help of many patient contributors. This particular book suffered many set-backs along the way, so I am particularly grateful to the authors herein. They demonstrated their compassion and exceptional professionalism throughout, by never second-guessing my decisions, and by allowing me to remedy the set-backs in my own way. They were a pleasure to work with, and they should take pride in their achievements."
