The origin of African American English, the informal dialect spoken by African Americans, has been a hotly debated issue in American linguistics. The main question has been whether the dialect is strongly determined by creole and ultimately African linguistic structures or whether it goes back mainly to British English dialect features. Edgar Schneider's dissertation (German 1981; revised American version 1989) systematically investigated this issue by analyzing old texts preserved verbatim in "ex-slave narratives"; it became widely known and influential in American sociolinguistics.
Since then this issue has continued to be a major topic of our research, partly in individual projects and partly in the compilation of large-scale text collections to investigate the issue. Notably, Alexander Kautzsch's dissertation (2002), also often quoted in the US, compares a range of available sources with the goal of analyzing ongoing change in the early African American English speech community; and the large-scale collaborative BLUR (with Ulrich Miethaner) and COAAL (with Lucia Siebers and Michael Montgomery) projects (see project separate descriptions) have provided extensive evidence on the nature of black dialect in earlier periods.
