Genre analysis has a long-established tradition in academic genres, but interest in the analysis of public genres has been very recent. This book examines the theory of genre analysis based on Swales' (1990) model; distinctive rhetorical features of English language newspaper Op- Eds were examined and found five obligatory moves including Relevant Headline, Introduction, Statement of the Problem, Argumentation, and Recommendation. There were also three optional moves called Sub-Headline, Background Information, and Starting with Argumentation.
