The Central Press Supervision Authority (HSTD) was a Soviet-style censorship authority, overseeing the circulation of information in Czechoslovakia in the 1950s and 1960s. The institution was set up in 1953 by a secret government order. At first it was subordinated directly to the presidency of the Czechoslovak government, however, after several months it was transferred to the Ministry of the Interior. The main aim of the HSTD was to ensure that materials containing secret or sensitive information were not published or disseminated to the public. In 1967, the HSTD was renamed the Central Publication Authority, and the following year, in 1968, this provisional censorship office was abolished.
