Tsentrizdat was established in 1924 to consolidate East and West publishing divisions into one entity. With a focus on literature, political, scientific and educational information in the national languages of the USSR, it had offices throughout the Soviet republics and autonomous regions. Tsentrizdat was dissolved in 1931 when the USSR centralized its printing and publishing industries.
Gostrudizdat (State Publishing House of Labor Issues) was established around 1924 as Labor Issues Publishing in order to disseminate printed material related to labor. Its office was located in Moscow at 6 Staraia (Old) Square in a building that also housed Moscow's Gorkom (city committee) and Obkom (oblast committee). Dominated by government institutions for decades, Staraia Square at one time contained the offices of the Central Committee of the Communist Party of the USSR.
