The report issued by the U.S. Arms Control and Disarmament Agency, in January 1975, concerns arms expenditures and sales made between 1963 and 1973. The 123-page document is composed mostly of two major parts: a country-by-country breakdown of arms trade for each of the years studied and a study contrasting each country's yearly military expenditures with its G.N.P., population size, and armed forces. The report (U.S. A.CD.A. Publication 74) may be purchased from the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 for $2. Persons ordering from abroad (other than Canada and Mexico) should add 25 percent to the price to cover shipping charges.
