The bulk of the material relating to the 1980 Moscow Olympic Games is held within the archive of the Russian State Archive of Contemporary History (RGANI). Between 2012 and 2013 the archive will be moving to a new building and their records are consequently not available for public consultation during that period.
RGANI has produced a 2-volume history of the Moscow Olympics, based around its holdings. Five Rings under the Kremlin Stars: Documentary Chronicle of the 1980 Olympics in Moscow is available through MIPP International.
Other records relating to the Moscow Olympics can be found among the holdings of Moscow City Archives
