The authors cite two large research open-access databases developed in recent years, popularly known by their acronyms PIDBA (Paleoindian Database of the Americas) and DINAA (Digital Index of North American Archaeology), for aiding in their study of early human settlements in Southeastern North America. With nearly half a million sites indexed so far, many with complex data records listing hundreds of attributes, DINAA has several orders of magnitude more information than PIDBA. PIDBA, however, encompasses image and attribute data on ca. 30,000 Paleoindian artifacts. Information recorded in both PIDBA and DINAA documents not only the number and distribution of Paleoindian artifacts and components found and recorded to date but also the possible proxy measures of human demography and settlement range, which can be compared with figures from later periods or from different states or regions.
