This book explores how interactions are achieved in new academic discourses, from both cross-genre and cross-disciplinary perspectives. By adopting a corpus-based analysis, it takes a detailed look at academic blogs, online book reviews, the abbreviated summary of article highlights, and the challenging postgraduate genre of the three-minute thesis. Through careful study of these discourses, the author aims to expand our understanding of the way researchers seek to make their work accessible to new audiences and create more egalitarian and engaging relations with them. Specifically, the author offers thoughtful analyses of the workings of stance and engagement to see how academics manage these new rhetorical challenges and reach out to both lay and specialist audiences. Through these analyses we gain new insights into both the genres themselves and how academics write in the twenty-first century. The book thus serves as an up to the minute work on new issues in the field of English for Academic Purposes.
