Main Directorate for the Protection of State Secrets in the Press under the Council of Ministers of the USSR (Russian: Главное управление по охране государственных тайн в печати при СМ СССР) was the official censorship and state secret protection organ in the Soviet Union. The censorship agency was established in 1922 under the name "Main Administration for Literary and Publishing Affairs at the RSFSR Narkompros", abbreviated as Glavlit (Главлит). The latter term was in semiofficial use until the dissolution of the Soviet Union.
Since the word "Glavlit" hints at "literature", the organization is often confused with Goskomizdat, which performed another type of censorship: it controlled the political content in fiction, poetry, etc.
