Mitrokhin Archive (nonfiction)

The Mitrokhin Archive is a collection of handwritten notes made secretly by KGB archivist Vasili Mitrokhin during his thirty years as a KGB archivist in the foreign intelligence service and the First Chief Directorate. When he defected to the United Kingdom in 1992 he brought the archive with him.

The official historian of MI5, Christopher Andrew, wrote two books, The Sword and the Shield (1999) and The World Was Going Our Way: The KGB and the Battle for the Third World (2005), based on material in the archives. The books purport to provide details about many of the Soviet Union's clandestine intelligence operations around the world.

In July 2014, the Churchill Archives Centre at Churchill College released Mitrokhin's edited Russian-language notes for public research; the archives are the largest openly available KGB data trove. The original handwritten notes by Vasili Mitrokhin are still classified.
