The view that academic discourse is, by definition, impersonal has long been superseded. It seems unquestionable now that the interpersonal component of texts, that is, the ways in which the writers project themselves and their audience in the discourse, is an essential factor determining the success of scholarly communication and has become a fundamental issue in the field of English for Academic Purposes (EAP).Interpersonality is the key issue around which the articles in this edited book focus on. The eighteen contributions included in this volume provide a wide exploratory view of the many academic genres in which interpersonality is manifested and the various analytical approaches from which the textual manifestation of that interpersonality can be studied. The varied origin of the contributors is also representative of the global interest that the issue of interpersonality arouses in the field of academic discourse analysis at an international level.The present volume constitutes a highly valuable tool for applied linguists and discourse analysts with an interest in EAP as well as for students, instructors and language teachers interested in academic discourse. The book may also be of interest to other agents intervening in the research publication process, such as translators, proofreaders, reviewers and editors.
