Craft of Political Research, The (Longman Classics in Political Science) (8th Edition)
"The Craft of Political Research is just what one hopes for in an undergraduate methods course. It is more theoretically engaged than most such texts, and the conceptual discussion is non-sectarian. Marx and Duverger make an appearance; so do Mancur Olson and Anthony Downs; so do Philip Converse and Robert Putnam. Students will learn that ideas matter, not the statistical software; and they will see that theoretical narrowness is the antithesis of good science."--from Christopher H. Achen's Foreword
