The Sourcebook of Family Theory and Research was sponsored by the National Council on Family Relations, the Research and Theory Section, and the Theory Construction and Research Methods Workshop. This is the collective effort of over 190 contributing scholars. The webpage provides additional information that the authors and editors agreed was important, but that did not fit into the page limits of the Sourcebook. Check back because some authors may update the ideas in their writings and features to keep current with developments in our field.
