As a field progresses, people write about their own work in journals, chapters, and books; but periodically the work needs to be collected and organized. It needs to be brought together in a format that can both introduce new members to the field and reacquaint continuing members with the work of their colleagues. Such a collection also affords an opportunity for the growing number of people with particular expertise to provide a reference for others whose work is related, but differs in focus. This is the first Handbook of Community Psychology. It contains contributions from 106 different authors, in addition to our editorial introductions. Its thirty-eight chapters (including two that are divided into multiple, individually authored parts) are concerned with conceptual frameworks, empirically grounded constructs, intervention strategies and tactics, social sys- tems, design, assessment and analysis, cross-cutting professional issues, and contemporary intersections with community psychology. Although interrelated, each chapter stands on its own as a statement about a particular part of the field, and the volume can serve as a reference for those who may want to explore an area about which they are not yet familiar. To some extent community psychologists eschew the distinction between researcher and practitioner; and regardless of one’s primary work environment (university, small college, practice setting, government, or grassroots organiza- tion), there is something of interest for anyone who wants to explore the community psychol- ogy approach.
