"This is an immensely useful book for sociologists working in a wide range of sub-fields. It confirms Freidson's status among the leading exponents of the old Chicago tradition. This book is catholic in its reading, sophisticated in its arguments and cautious in its judgements."—Robert Dingwall, Sociology

"As an attempt to provide a complex, wide-ranging account this book should be essential reading for specialist students, and it should act as a stimulus for the extension of both empirical research and theory."—Alex Faulkner, Sociological Review

"Freidson's book is a concise introduction to the professions, challenging specialists with its puncturing of theoretically induced misconceptions and offering general readers a clear but critical entrée to the theoretical literature concerning this central aspect of modern society."—Andrew Abbott, Science

"This is a stimulating and well-written book which opens up a new perspective on the professions as well as contributing to existing debates."—David Podmore, Times Higher Education Supplement
