"Over 20 years after being smuggled out of Russia, a trove of KGB documents are beingopened up to the public for the first time. The leaked documents include thousands of files and represent what the FBI is said to view as "the most complete and extensive intelligence ever received from any source." The documents include KGB information on secret Russian weapons caches, Russian spies, and KGB information on the activities of Pope John Paul II. Known as the Mitrokhin Archive, the files are all available as of today at Churchill College's Archives Centre."
