"This book makes for truly engaging and interesting reading! It is packed with useful analyses, examples, and discussions of the methodologies and epistemologies surrounding case study research. The wealth of diverse illustrations from the SLA literature also makes it a very important resource for graduate students. I hope many applied linguistics programs take advantage of this excellent textbook and begin offering courses on case study methodology!" - Lourdes Ortega, University of Hawai'i
"The book can serve as an effective resource for qualitative research professors in their preparation of course modules as well as for graduate students and more experienced researchers in the field of applied linguistics...Duff has been able to both offer a balance of conceptual and practical guidance and skillfully engage with different levels of inquiry (epistemology, ontology and methodology) throughout the book." - Marzieh Tafaghodtari, University of Ottawa
"...this volume is a welcome addition to the AL research community, and both beginning and seasoned AL researchers will find it useful."

"Case studies are a widely-used research method in applied linguistics today, notably in the context of second language learning, teaching and use. For anyone not acquainted with this qualitative approach, Duff’s book serves as an excellent introduction to its distinctive attributes, the associated theoretical issues and to the practicalities of conducting, evaluating and presenting case study research."
