Having authors in the Netherlands and Australia collaborate on a book, despite the presence of the Internet, is always difficult. Fortunately VU University Amsterdam is close to Schiphol Airport, and John Zeleznikow regularly visited whenever he was in Europe for a conference. So Amsterdam was always en route from Australia: whether it was via Boston, Lisbon or Tel Aviv. We are grateful to the Australian Research Council and Victoria University for providing the funding for Professor Zeleznikow to visit Dr Lodder.

As with any worthwhile venture, this book relied upon the efforts of many to reach fruition. We are thankful to the countless individuals who contributed in a variety of ways.

Almost a decade ago, while Arno Lodder was just beginning his exploration of the field of technology-enhanced dispute resolution, he held an instructive discussion with two leading, ground-breaking figures in the field: Ethan Katsh and Colin Rule, who were then visiting The Hague. The discussions were invaluable and Dr Lodder and Professor Zeleznikow are very thankful for the regular dialogues they have held since then.

It is not possible to mention all those who collaborated on projects relevant to this book. However, important contributions to Dr Lodder's work (listed in random order) are: Gerard Vreeswijk, Berry Zondag, Stephanie Bol, Frank van Harmelen, Michel Klein and Paul Huygen. His colleagues at VU Amsterdam University provided a rich and pleasant working environment, and in particular he had numerous stimulating discussions with Rob van den Hoven van Genderen.
