Book excerpt: The Studies in Japanese and Korean Historical and Theoretical Linguistics and Beyond presented in honour of Prof. John B. Whitman includes contributions by a range of mid-generation to senior scholars among his closest colleagues and collaborators representing the front line of contemporary research in the areas of historical and theoretical linguistics of Japanese and Korean as well of Chinese, Turkish, and Russian. Particularly, in all these areas it deals with still ongoing debates about the important issues in historical and theoretical linguistics concerning these languages that are reflected in articles often representing opposing points of view. This book can serve as a good introduction to the current state-of-art and the most essential problems in the fields it covers.
