This is a landmark textbook. Being thoroughly grounded in empirical research on interpreter-mediated interaction and institutional discourse, it deserves a wide readership, not only among students of interpreting and early-career interpreters, but also among those who are dependent on interpreter-services as public-sector professionals. Cecilia Wadensjo, Stockholm University, Sweden This book contains a unique blend of theory and practice that is rare in academic publications. Its breadth and depth are truly impressive. Most innovative are the recommended activities in each chapter, focusing on research, performance skills and collaborative dimensions. Instructors and learners alike will find this work extremely useful. Holly Mikkelson, Middlebury Institute of International Studies at Monterey, USA
