The preface which initiates textbooks is a significant convention in writing academic textbooks as it introduces the book, explains assumptions, clarifies expectations, and convinces the readers to read on. In the present study, using Martin and White’s (2005) Appraisal framework, ninety textbook prefaces written by both native and nonnative writers, in both hard and soft sciences, were selected and analyzed aiming at exploring writers’ preferences for the type and frequency of appraisal resources. The statistical analysis of the data revealed that the writers plentifully used appraisal resources in the prefaces to express their attitudes, positions, and goals of the inclusion of various sections in the book. Attitude resources, in terms of frequency, are the most frequent, and Engagement elements are the least with Graduation items coming in the middle position. This is quite natural as all academic writing is to express opinions and positions, and prefaces, specifically, are less probable to indicate others’ attitudes and stances, but the authors’ positions and purposes behind the book. Based on the findings, it is concluded that native textbook writers are superior to nonnative writers in terms of communication power, establishing solidarity, and a convincing and forceful voice. The frequency of the subsystem of the main appraisals is also detailed in the article. This study can have implications for textbook writers, teachers, EFL learners, and materials developers.
