The CIA has released two collections of previously classified historical documents. The first collection, called "Family Jewels," contains responses to a 1973 directive from then Director James Schlesinger asking CIA employees to report activities that "might be inconsistent with the Agency's charter."
The second collection, the CAESAR-POLO-ESAU papers, focuses on Soviet (CAESAR) and Chinese (POLO) leadership hierarchies, and Sino-Soviet relations (ESAU) from 1953 to 1973.
