Giovanni Sartori Award for the Best Book Published in 2007 Developing or Applying Qualitative Methods - Honorable Mention'...an impressive collection of essays that survey the ways in which necessary conditions counterfactuals are used in the logics of causal explanation, particularly in explanations of international conflict. The work represents an important contribution to the study of methods in general and usefully develops some central concepts in qualitative research. The substantive focus also helps to elucidate the more abstract theoretical discussions.'Newsletter of the American Political Science Association
