Just finished reading this series. It was quite comprehensive, but I feel a bit too technical for most interested laypeople such as myself. Still I got a lot from it and learned a lot from it. Anyone else read it? What did you think?
J.C. Wells' Accents of English series
I think it is something of a specialised interest.
