Linguistic Diversity and National Unity: Language Ecology in Thailand

[Eric Muller]

I just finished reading âLinguistic Diversity and National Unity: 
Language Ecology in Thailandâ  by William Smalley, University of Chicago 
Press, ISBN 0-226-76288/9, and I found it very interesting. However, I 
have no reference to judge it against.  Can anybody comment on it? Any 
significant change since it was published 10 years ago?

Thanks,
Eric.
