This is a very colloquially written but comprehensive survey of Ozark dialect. The authors discuss the history of Ozark dialect, regional variations, grammar, euphemisms, taboos, use of the dialect in fiction, and end the book with a glossary of Ozark words and phrases.
It's not organized like a reference book, so it's not easy to find a particular phrase or term, but if you are looking for an interesting read about Ozark customs and language, or want to get a good feel for the dialect for writing purposes, this is an excellent book.
