In this most extensive revision of their classic text for social workers, Rubin and Babbie retain the integrity of their comprehensive, quantitative approach, while including more content about qualitative methods. As one pre-publication reviewer pointed out, ''With this edition, you have solved a problem in the discipline by infusing coverage of qualitative issues where it is most important". Past editions were acclaimed for the depth and breadth of coverage and the clear and often humorous writing style. Without losing those winning qualities, the authors have created a text that is even more cutting edge. It now provides updated coverage of the technology of research and offers a variety of alternative approaches to doing applied social work research in agency settings.
