The Vietnamese in Oklahoma City: A Study of Ethnic Change

By Charles C. Muzny, AMS Press, 1989

I've not been able to find any information on this title other than that it exists and that it might still be possible to purchase through AMS Press.  This book was part of a series of publications looking at ethnic populations in cities across North America.
