I have resisted the term sociolinguistics for many years, since it implies that there can be a successful linguistic theory or practice which is not social.

I am now completing research supported by NSF and NEH that is mapping changes in the English language through all of North America, for both mainstream and minority communities.

It appears that the present-day form of African American English is not the inheritance of the period of slavery, but the creation of the second half of the 20th century.

We focus upon pairs of words very often which are the same in some areas and different in other areas.

An important aspect of the current situation is the strong social reaction against suggestions that the home language of African American children be used in the first steps of learning to read and write.

But unlike European countries, America has never finished a map of the United States, only the eastern United States is covered and a few spots here and there.

Well, American dialects have been studied for a hundred years or so.
