Documents / FOIA release
This is Volume Three of the CIA Directorate of Science and Technology Historical Series on the Office of Scientific Intelligence (OSI), 1949 to 1968, written by Karl H. Weber in June 1972 and approved for release in 2008. It holds three annexes, on OSI publications, OSI's external assistance and contracting program, and OSI's interaction with the National Security Agency. The released text covers production planning, review boards, current intelligence periodicals and future threat forecasting. It does not discuss UFOs.
During the International Geophysical Year, OSI initiated the production of the International Geophysical Year Briefs. These Briefs, which reported important foreign activity related to the IGY on a current basis, were published biweekly on the average. The first was issued on 13 September 1957 and the series was discontinued with issue No. 37 of 15 January 1959. Another periodic OSI publication was the informal Current Activity and Highlight Brief. The Briefs contained both substantive and personnel information. They were disseminated within the Agency and there is some evidence that at least selected issues were sent to the Air Force. The publication apparently began in 1960 and continued at least to mid-1961.
