The physical papers were deposited at the Churchill Archives Centre at Churchill College, Cambridge. In 2014, the center opened Mitrokhin’s edited Russian-language notebooks to the public. Scholars can view digitized versions of these original papers. Researchers looking for the most authentic primary source material should consult the Churchill Archives digital finding aids. 2. The Wilson Center Digital Archive
The Mitrokhin Archive is a collection of handwritten notes and documents copied covertly by Vasili Mitrokhin, a senior archivist in the Soviet Union’s Main Archive Directorate (the KGB’s archive administration). Smuggled out of Russia after Mitrokhin defected to the United Kingdom in 1992, the archive provided detailed allegations about Soviet intelligence operations, foreign agents, active measures, and covert influence campaigns spanning the Cold War. The material ignited major scholarly, journalistic, and intelligence interest because it claimed to reveal KGB activities across Europe, the Americas, Asia, and the developing world.
As modern intelligence threats increasingly rely on digital disinformation and cyber warfare, the Mitrokhin Archive serves as a vital historical roadmap, showing that today's headlines often stem from tactics perfected by the KGB decades ago.

The Mitrokhin Archive represents one of the most significant intelligence coups in history, providing an unprecedented, top-secret look into the operations of the Soviet KGB. Smuggled out of Russia in 1992 by Vasili Mitrokhin, a senior KGB archivist who became a secret dissident, the archive consists of thousands of handwritten notes detailing operations from the Bolshevik Revolution to the 1980s. While often sought in format, the core of this intelligence is published in two comprehensive volumes co-authored with historian Christopher Andrew: The Mitrokhin Archive: The KGB in Europe and the West and The Sword and the Shield .

The publication of the archive sent shockwaves through Western intelligence agencies, leading to the exposure of numerous deep-cover Soviet agents (known as "illegals") and historical secrets. 1. Infiltration of Western Infrastructure
Vasili Mitrokhin worked in KGB archives for decades, giving him access to internal reports, cables, agent files, and operational summaries. Over roughly 12 years before his 1992 defection, Mitrokhin painstakingly transcribed thousands of pages of notes from original documents, avoiding removal of the originals. He carried these notes out when he ultimately defected with his family to Britain. British intelligence (MI6) debriefed him and authenticated portions of the archive against available documentation, then collaborated with historians and publishers to disseminate portions publicly.
The Mitrokhin Archive offers unparalleled insights into the KGB's activities, motivations, and goals. The documents reveal:
Starting in 1972, Mitrokhin was tasked with supervising the transfer of millions of KGB files from the Lubyanka to a new headquarters. Taking advantage of his access, he spent secretly copying documents by hand.
