A second major initiative was identifying and inventorying all cemeteries in Pushmataha County. Several states throughout the U.S. have begun the process of mapping and inventorying subaqueous soils. Receiving, inventorying, and storage operations were conducted daily for 90 consecutive days. Additional volumes inventorying musical autographs, musical scores, and iconography were planned but were never published. These stores began to lose money due to lack of loss prevention and throwaway inventorying. The inventorying of the numerous works is under way. The Corporation for Public Broadcasting (CPB) began inventorying US public media content in 2007.
