The material presented in this book comes from a wide range of sources. Apart from recourse to secondary sources and commentaries on the judicial process in this area, we have drawn on a number of government reports dealing with cyber crime. The Internet itself provides a good deal of information, and of course many unreported judicial decisions are now available online.

In addition, we sought input and advice from senior practitioners in the field. This was achieved through informal discussions with personal contacts and, more formally, by holding a number of Roundtable Discussions in which we called together the most senior people in a variety of jurisdictions who are involved in the investigation and prosecution of cyber crime. The purpose of these was to seek their understanding of the key issues that affect their daily work.

Two such Roundtable Discussions were held, one in Canberra on 4 April 2002 at the Australian Institute of Criminology and one in London on Tuesday 16 July 2002 at the Home Office. In the United States, discussions were held with key informants in Washington DC on 7 and 8 November 2002. Attending each were senior police, prosecutors and/or representatives from regulatory agencies in each country, with each discussion facilitated by one of the authors. Each discussion followed the plan of the chapters of this book.
