Kelly Ritter and Paul Kei Matsuda have created an essential introduction to the field of composition studies for graduate students and instructors new to the study of writing. The book offers a careful exploration of this diverse field, focusing specifically on scholarship of writing and composing. Within this territory, the authors draw the boundaries broadly, to include allied sites of research such as professional and technical writing, writing across the curriculum programs, writing centers, and writing program administration. Importantly, they represent composition as a dynamic, eclectic field, influenced by factors both within the academy and without. The editors and their sixteen seasoned contributors have created a comprehensive and thoughtful exploration of composition studies as it stands in the early twenty-first century. Given the rapid growth of this field and the evolution of it research and pedagogical agendas over even the last ten years, this multi-vocal introduction is long overdue.
