The expansion of the Internet and computing technologies has transformed, heuristically, methodologically, and epistemologically, the scholarship on modern Atlantic slavery and the slave trade. An increasing number of primary and secondary sources are now available online. Archives, universities, libraries, research centers, and other institutions have digitized partially or entirely historical collections and archival records and made them public through digital portals in a variety of formats. Users can instantly access, analyze, search, share, transfer, visualize, and interact with a vast amount of historical data on slavery and the slave trade, which, in the late 20th century, was scattered across archives and libraries. The increasing Web presence of digital repositories on Latin American historical slavery and the slave trade is changing previous scholarly perceptions about broader demographic, historical, and social issues, as well as about the everyday life of enslaved Africans. Digital databases on the slave trade, for instance, are answering long-term historiographical concerns regarding the number of captives carried to the Americas, their African embarkation regions, or the nationality of the carriers. Digital repositories and databases help to better understand the African geographical origins of the slaves and their ethnicities, a key component in the formation of the Afro-Latin American culture. Digitized repositories such as baptismal, marriage, and burial archival records and databases on runaway or self-liberated slaves, plantation lists, or court cases are filling gaps in scholars’ understanding of the internal dynamics of the institution of slavery, which characterized most of Latin American history for about three centuries.
