Drs. Mike Shott (University of Akron) and Kevin Nolan (Ball State University) have organized the Central Ohio Archaeological Digitization Survey (COADS) to undertake a concerted effort to engage the artifact collectors and archaeology enthusiasts in central Ohio in building out a more complete and more accessible record of the prehistoric past of the region. Recognizing that the vast majority of artifacts and sites are contained in private collections, Shott and Nolan seek to bridge this void in the academic record of the region. The full story of how prehistoric cultures coped with adversity and environmental change demands incorporating into archaeological research the knowledge that resides in private collections. The Central Ohio Archaeological Digitization Survey (COADS) is the first systematic effort to map and digitize collections from a specific region of the United States, the remarkable prehistoric landscape of Ohio's central Scioto Valley. One of its chief innovations is to treat local knowledge as integral to the archaeological record and research. In the process, COADS documents prehistoric cultural transitions as responses to population growth, economic change, and landscape development. It uses archaeology's unique perspective to study tempo and mode of long-term technological change. COADS integrates the materials from private collections with previous site- and region-based analyses into a composite model of distribution of human activity on the landscape over time. Previous work constructed a mutually reinforcing model of transition from mobility to residential stability (i.e., more sedentary populations) concomitant with a shift to increasing focus on, and eventual domestication of, seed crops.
