Writing a book review is an instance of evaluative academic writing where the writer is involved in an interaction with the author and the reader, evaluates the viewpoints stated in the book and voices his own position and stance in a dialogue with the reader. Working within the framework of Martin and White’s (2005) Appraisal Theory as an effective tool for studying the essential resources employed in this interaction and evaluation, the present study examined 60 book reviews from the Humanities academic journals written by native male and female writers, and tried to investigate the type and frequency of the three Appraisal categories (Attitude, Engagement, Graduation). The findings indicate that both writer groups made extensive use of these resources in their writings. However, the male book review writers exceeded the female writers in all the three categories. In addition, the Attitude resources were used the most and The Engagement resources were the least employed resources. The implications of the study for teaching writing skills and developing materials and tasks for writing courses at academic levels are mentioned in detail
