Book excerpt: In Writing Genres, Amy J. Devitt examines genre from rhetorical, social, linguistic, professional, and historical perspectives and explores genre's educational uses, making this volume the most comprehensive view of genre theory today. Writing Genres does not limit itself to literary genres or to ideas of genres as formal conventions but additionally provides a theoretical definition of genre as rhetorical, dynamic, and flexible, which allows scholars to examine the role of genres in academic, professional, and social communities. Writing Genres demonstrates how genres function within their communities rhetorically and socially, how they develop out of their contexts historically, how genres relate to other types of norms and standards in language, and how genres nonetheless enable creativity. Devitt also advocates a critical genre pedagogy based on these ideas and provides a rationale for first-year writing classes grounded in teaching antecedent genres.
