As emerging themes, English for Specific Purposes (ESP) and English for Academic Purposes (EAP) have witnessed rapid progress due to the increasing role of English as an international language (Kırkgöz & Dikilitaş, 2018). Nonetheless, with a few notable exceptions (Charles, 2014; Lee & Swales, 2006), there seems to be a dearth of research and firsthand resources in the utilization of corpora in ESP and EAP. Spotting this visible gap, this volume edited by Charles and Frankenberg-Garcia is a valuable resource, which offers a state of the art and an ample ground approach to targeting corpus methodology in ESP and EAP. The volume, published by Routledge, is an impressive and rich work of scholarship for serious readers and seasoned researchers in which contributing authors, in seven units and 3 parts, skillfully and succinctly provide an exploration of the salient role of corpora in ESP and EAP. The structural sequence of the chapters, as well as their selection, makes this book a stimulating read and warrants its place in the resource collection of this area of research. The volume provides a comprehensive account of the multifarious applications and implications of the corpus approach in ESP and EAP. The editors have been able to convene renowned and preeminent scholars to produce a resource book. At its heart, the contributors' innovations register the corpus approach as an emerging theme in ESP and EAP research. The introductory chapter is an overview of the content of the book as well as a succinct overview of the different types of corpora, including target language, interlanguage, specialized, general, and ready-made, as well as their constructive roles for ESP and EAP and the effectiveness of data-driven learning (using learners' conscious raising and noticing) in the writing classroom. The first part of the book is dedicated to the way corpora are (or can) be used for conducting research in ESP and EAP. A major role of corpora is their application in lexicography and phraseology, as they can provide the reader with authentic texts and illustrative materials (Gizatova, 2018). In addition to lexicography, a dedicated focus on corpora in academic writing deserves attention (Römer, 2010). Thus, in reading the two chapters of part 1, the reader is fascinated to witness how corpora are used in academic writing. The role of corpora in teaching English has been stressed by researchers (Boulton & Cobb, 2017; Zufferey, 2020). The role of corpus in ESP and EAP is elaborated in part 2, where the focus is on the exploitation of corpora and their potentiality in ESP and EAP. This is shown in chapter 3 (by Liou and Liu), where the corpus is seen as a method of corrective feedback for English learners, and in chapter 4 (by Ackerley) where a genre-specific corpus is utilized for ESP writing research.
