"The Comprehensive Handbook of Social Work and Social Welfare is an outstanding contribution to social work literature. The Handbook offers a unique and practical view of social work. We recommend that all academic libraries adopt this volume. Social work professors need to review it. These volumes will make significant contributions to student learning."
