Academic vocabulary is in fashion as witnessed by the increasing number of books published on the topic. In the first part of this book Magali Paquot scrutinizes the concept of academic vocabulary and proposes a corpusdriven procedure based on the criteria of keyness range and evenness of distribution to select academic words that could be part of a commoncore academic vocabulary syllabus.In the second part the author offers a thorough analysis of academic vocabulary in the International Corpus of Learner English ICLE and describes the factors that account for learners difficulties in academic writing. She then focuses on the role of corpora and more particularly learner corpora in EAP material design. It is the first monograph in which Grangers 1996 Contrastive Interlanguage Analysis is used to compare 10 ICLE learner subcorpora in order to distinguish between linguistic features that are shared by learners from a wide range of mother tongue backgrounds and unique features that may be transferrelated.
