Two convictions lie at the heart of this volume. First, area studies scholarship remains indispensable for the social sciences, both as a means to expand our fount of observations and as a source of theoretical ideas. Second, this scholarship risks becoming marginalized without more efforts to demonstrate its broader relevance and utility. Comparative Area Studies (CAS) is one such effort, seeking to balance attention to regional and local contextual attributes with use of the comparative method in search of portable causal links and mechanisms. CAS engages scholarly discourse in relevant area studies communities while employing concepts intelligible to social science disciplines. In practice, CAS encourages a distinctive style of small-N analysis, cross-regional contextualized comparison. As the contributions to this volume show, this approach does not subsume or replace area studies scholarship but creates new pathways to “middle range” theoretical arguments of interest to both area studies and the social sciences.
