"It is evident that comparing American history internationally is an idea whose time has returned. Perhaps Woodward's Comparative Approach will have a greater impact this time around. Its shortcomings and omissions are more obvious now, but so are its strengths: its call to make American history more cosmopolitan, its devotion to the nation as a unit of analysis, its still-provocative individual essays, its openness to a variety of comparative techniques, and its avoidance of specialized jargon. As we set out to broaden our audience and internationalize our outlook, we ought to profit from its example."--Carl J. Guameri, Reviews in American History
