Sponsored by the National Council on Family Relations the <strong>Sourcebook of Family Theory and Research</strong> is <i>the</i> reference work on theory and methods for family scholars and students around the world. This volume provides a diverse eclectic and paradoxically mature approach to theorizing and demonstrates how the development of theory is crucial to the future of family research. The <strong>Sourcebook </strong>reflects an interactive approach that<b> </b>focuses on the process of theory building and designing research thereby engaging readers in doing theory rather than simply reading about it. An accompanying Web site http://www.ncfr.org/sourcebook offers additional participation and interaction in the process of doing theory and making science.
