Linguistic Atlas of the Gulf States

The Linguistic Atlas of the Gulf States (LAGS) is a linguistic atlas documenting the dialects of eight Southern states: Florida, Georgia, Tennessee, Alabama, Mississippi, Louisiana, Arkansas, and Texas. Directed by linguist Lee Pederson at Emory University, the project collected data from 914 speakers between 1968 and 1983. The atlas was published in seven volumes by the University of Georgia Press between 1986 and 1992.

LAGS was notable for introducing quota sampling to American dialectology and for pioneering computerized analysis of linguistic atlas data through an "automatic atlas" system. The project's approximately 1.2 million responses represent one of the largest dialect surveys conducted in the United States.
