Malcolm W. Klein Center for Research on Crime and Social Control University of Southern California 1. BACKGROUND In June of 1988, approximately forty scholars and researchers met for four days in the Leeuwenborst Congres Center in Noordwijkerhout, The Netherlands, to participate in a workshop entitled Self-Report Metho­ dology in Criminological Research. The participants represented 15 nations and 30 universities and research centers, a diversity that was matched by the experiences and focal interests in self-report methods among the participants. This volume is the result of the workshop process and in particular of the invitations to participants to prepare pre-conference papers for distribution prior to the workshop. The chapters in the volume were selected from the larger set of pre­ conference papers. As workshop conv~ner and volume editor, it falls on me to set some of the context for this enterprise. Self-report crime is "admitted" crime, derived from interview and questionnaire responses obtained from adults and juveniles (regardless of whether or not they have been arrested) concerning their own illegal behaviors. Growing awareness of the limitations of official crime statistics has led to the development of self-report procedures.
