The Applied Anthropology Laboratories (AAL) is an outreach arm of the Department of Anthropology at Ball State University. In a collaboration between the Director, Kevin C. Nolan, and Michael Shott of the University of Akron, they built the NSF-funded project 'COADS', documenting approximately 20,000 artefacts from hundreds of sites in private collections in central Ohio. The 3D models produced in this collaboration have been made publicly available online for the public to use for research or general interest.

In archaeological terms, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a spear, dart, or arrow, or perhaps used as a knife.
Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites, providing useful clues to the human past, including prehistoric trade and cultural tendencies.
