Co-published by the National Association of Social Workers and Oxford University Press, the 20th edition of the Encyclopedia of Social Work is widely considered the cornerstone of reference in its field. This new edition includes coverage of areas that have come to the fore since the 1995 publication of the 19th edition, including demographic changes from immigration, technology, the implications of managed care, faith-based assistance, evidence-based practice, gerontology, and trauma and disaster.

The Encyclopedia contains four hundred subject entries and two hundred brief biographies of key figures in the history of social work. Clearly arranged in A-Z format, each article is fully cross-referenced and includes a select bibliography to guide interested readers to primary sources and the most important scholarly works on a given subject. The work also includes a comprehensive index and topical outline. Comprehensive in coverage and international in scope, the Encyclopedia is a valuable resource to social work practitioners, scholars, and students alike.
