The increase of crime at the national, transnational and international levels has heightened concern in the international community and generated greater interest in international criminal justice policy. Since the 1950s, the United Nations has been developing the Crime Prevention and Criminal Justice Programme, which was designed to respond to these concerns. But United Nations resources and support for the programme have been limited, notwithstanding the services and contributions of the Crime Prevention and Criminal Justice Branch.;The information contained in this book highlights the significant contributions of a number of organizations, whose work may not be sufficiently known outside the circles of scholars, experts and professionals in the field of international criminal justice. The book is thus also a tribute to these organizations, giving greater publicity to what they have contributed over the years.
