Digital Library on American Slaveryoffers data on race and slavery extracted from eighteenth and nineteenth-century documents and processed over a period of eighteen years. The Digital Library contains detailed information on about 150,000 individuals, including slaves, free people of color, and whites. These data have been painstakingly extracted from 2,975 legislative petitions and 14,512 county court petitions, and from a wide range of related documents, including wills, inventories, deeds, bills of sale, depositions, court proceedings, amended petitions, among others. Buried in these documents are the names and other data on roughly 80,000 individual slaves, 8,000 free people of color, and 62,000 whites, both slave owners and non-slave owners.
