This book is directed at lexicographers and professionals in Translation Studies and English Language Teaching. Chapters by translation scholars alternate with chapters by teachers of English; within them, sections on the contents of the works discussed alternate with sections on their use and/or usability. Each of the chapters offers a glimpse of interesting research possibilities that practice raises, the issues we need to investigate and explain, as well as how to turn some of this research into practical action. The book proves that dictionaries continue to play an important part in our daily and academic lives, though it is not always clear how they should fit into the overall pattern of curriculum design, teaching materials or learning styles.
