Journal of the Society of Motion Picture Engineers (1930-1949)

156 CLASSIFIED INDEX AMERICAN STANDARDS American Standards on Motion Pictures first appeared in 1930 and were pub- lished by the Society in that year. Many changes have since been introduced and published in the JOURNAL to keep the industry aware of current improvements and of new technical developments as they began to attain a position of economic importance. In 1945, following the end of emergency War Standards activity, ASA Com- mittee on Motion Pictures, Z22 recommended revision of all existing Standards within its field of interest. The ASA chose that as an opportune time to change the size of its Z22 Standards from 5x8 inches to 8 l /2 x 11 inches, perforated to fit a standard three-post loose-leaf binder. At the request of its own Standards Committee and through arrangement with the ASA, the SMPE made a binder for these Standards available to the industry. That binder, together with a com- plete set of Standards current at the time of order, may now be purchased from the Society at a reasonable discount. Industry people who purchase binders are notified of all new Standards at the time of ASA approval and are thus assured that their records are accurate and up-to-date. The Standards, in complete sets only, with the loose-leaf binder, may be pur- chased from the Society of Motion Picture Engineers 342 Madison Avenue New York 17, N. Y. A complete Index to all American Standards, including those on Photography and Motion Pictures, may be secured at no cost by writing to the American Standards Association 70 East 45 Street New York 17, N. Y. Individual copies of Standards on Motion Pictures, Photography, or other subjects must be purchased directly from the ASA. Printed in U.S.A.
