Handbook of the Linguistic Atlas of the Middle and South Atlantic States by William A. Kretzschmar Jr. (Editor)
This book does not contain much linguistic data per se, but it is an extremely useful work for those who make frequent use of the Linguistic Atlas records. Much of the book is taken up in community and informant sketches: each and every locality surveyed is listed, along with a sketch of its settlement history. A short paragraph is devoted to each LAMSAS informant: occupation, age, family history, and various other notes. Other features of this work include notations on the fieldworkers' transcriptional peculiarities, and maps showing the locations of each informant. Not recommended for those with merely a casual interest because of its technical nature, but indispensable for those delving into the intricacies of the LAMSAS data.

**NEW** Dictionary of American Regional English, vol. 4: P-Sk Frederick G. Cassidy (Editor), Joan Houston Hall (Editor)
The Dictionary of American Regional English (DARE) is not fully published yet, but what has already been released is nothing short of outstanding. Here for the first time we see a massive compilation of data ranging from Linguistic Atlas-style interviews, to thorough historical and literary citations, to odd notations collected right on up to the present. It is no exaggeration to call this the ne plus ultra of American dialect lexicology. Even if your interest is only in one specific area of the country, DARE can be of great help in determining what the true extent of those "local" words really are. The first volume contains introductory chapters on typical changes in American folk speech, a guide to pronunciation, the text of the DARE questionnaire, and a listing of all the informants and their relevant biographical information. The dictionary itself is in a very readable and reference-friendly style, and it actually makes fun browsing.

American Regional Dialects : A Word Geography by Craig Carver
This book is an analysis of the lexical data collected from the DARE surveys, and makes a good companion to the DARE Dictionary. A good book if you want to know what the general dialect picture of the country looks like, and how the various dialects relate to each other.
