The Corporate Source Authority System (CSAS) lists all organizations that have contributed information to any of DTIC's three major databases (Technical Reports, Research Summaries and IR&D). Each organization is assigned a 6-digit Source Code used to search these databases for information authored or sponsored by the organization. Each Corporate Author record displays the root (highest) element of the organization, the parent (next higher) element of the organization, any sub-organizations or former names, and the organization's Source Code.
