Dictionary of American Regional English
Explore the links that offer a taste of the kind of information gathered in the decades-old project called The Dictionary of American Regional English, which recently published the final volume of their massive reference work. Examine a Sample Page. Survey a large selection of sample entries. How many of these words do you recognize? Listen to some audio files, including 'Arthur the Rat', in which Americans from different regions are pieced together in an audio collage to show the impressive range of dialects. Most of the information was collected in the middle of the twentieth century, and most of the informants were older people who lived their lives in one region.
This link will take you to the African-American and Gullah Project of the Linguistics Atlas Projects website. The Gullah part makes use of the data gathered by Lorenzo Dow Turner, which went in to his 1949 book. Some of the informants he interviewed were born into slavery. Use the "Browse" button to see a list of informants (identified by an alpha-numeric code), and then follow that link to explore the information collected from them.

Linguistic Atlas and Mapping Projects
The Linguistic Atlas Project: spend some time exploring this database. Does the information it gives for the dialect in the regions that you know line up with what you hear? Bring your observations to section.
The Telsur Project (includes North American regional dialect maps). You might begin with the maps (link near the top of page). See, for example, the map of the pin/pen merger in the southern US. Spend some time exploring, and bring your observations to section.
