The purpose of this series is to provide an overview of recent research de- velopments in the field of alcoholism so that interested professionals and researchers may keep abreast of this complex, multidisciplinary work. These annual volumes will present a scholarly review and analysis of selected re- search topics prepared by leading figures in the field. Where appropriate, the attempt is made to present contrasting perspectives and views, particularly on issues where there is ongoing controversy. The American Medical Society on Alcoholism and the Research Society on Alcoholism have undertaken this collaborative venture because of the perceived need for such a comprehensive resource. These groups are both component organizations of the National Council on Alcoholism, a broad- based coalition which supports alcoholism treatment, training, and research on a national and international level. This professional network has enabled us to draw on a panel of Associate Editors and on authors of international prominence. The series should reflect a sophistication that will allow it to serve as a standard reference for the field.
