The Old Believers 

On May 31, 1990, during the US/Soviet summit, the Library of Congress opened an exhibition of rare Russian manuscripts. Some of the books had been concealed for centuries by the Old Believers, who had fled from persecution to the frontiers of the Soviet empire and beyond. The Old Believers are a unique part of Russia's rich cultural heritage and the legacy of their manuscripts speaks across generations.
This rough-cut documentary about the exhibit features James Billington, Abby Smith, Raisa Gorbachev, and a glimpse of Old Believers in America.
