Government discovers method to preserve movie film indefinitely. Washington, D.C., July 8. People living in the year 2000 will be able to see and hear today's history in the making through experiments on preserving movie film now being conducted by the National Bureau of Standards.

These tests showed that cellulose, or explosive film, would last from 50 to 100 years. The new Safety or Acetate film "may be preserved for longer periods." Unofficially, the experts put the figure at several hundred years. The following set of pictures were made at the Bureau of Standards and the National Archives Building.
