These specially-commissioned studies cover corpus-informed approaches to researching, teaching and learning English for Specific Purposes (ESP). The corpora used range from very large published corpora to small tailor-made collections of written and spoken text, as well as parallel and contrastive corpora, in both the hard and softer sciences. Designed to tackle the problems faced by a variety of first- and second-language ESP users (specialised translators, undergraduates, junior and experienced researchers, and language trainers), the breadth of approaches enables treatment of issues central to ESP and corpus research, from corpus compilation and analysis to new applications and data-driven learning. The first full-length book on applied corpus use in France, Corpus-Informed Research and Learning in ESP will be of interest not only to those working in the French context, but to a wide variety of language professionals - teachers, researchers or course designers - in many countries looking at ESP from different linguistic, cultural and educational perspectives.
