Building on the successful 1st edition, this reader brings together some of the most significant ideas that have informed social work practice over the last fifty years. At the same time as presenting these foundational extracts, the book includes commentaries that allow the reader to understand the selected extracts on their own terms as well as to be aware of their relations to each other and to the wider social work context. There is no settled view or easy consensus about what social work is and should be, and the ideas reflected in this volume are themselves diverse and complex. The world of social work has changed greatly over the last ten years, and this new edition reflects that change with new material on the decolonisation of social work knowledges, the greater emphasis on inter-disciplinarity and co-production and the new concern for identities. With an accessible introduction to contextualise the selections, the book is divided into three main sections, each presenting key texts drawn from a wide range of perspectives: psychological, sociological, philosophical, educational and political, as well as perspectives that are grounded in the experiences of practitioners and those who use services, which have contributed to the development of:the profession of social workknowledge and values for social work andpractice in social work. By providing students and practitioners with an easy way into reading first-hand some of the most interesting, foundational texts of the subject, it will be required reading for all undergraduate and postgraduate programmes and professionals undertaking post-qualifying training.
