Mospoligraf was a state-owned printing trust located in Moscow. When the Soviet Union formulated a plan in 1921 to consolidate the nation’s largest and best printing operators into state-owned trusts; Mospoligraf was organized in 1922 to carry out consolidation of the Moscow printing industry. With a staff of over two thousand, Mospoligraf was the second-largest printing trust organized in Moscow outside of the Mospechat’ trust, and it oversaw a myriad of houses under local printing sections such as the 2nd Chromolithography Workshop, the 5th Lithography Workshop, the 7th Typography Workshop and the 26th Lithography Workshop, to name a few. After a reorganization, the trust leased its operators. For example, two printers under Mospoligraf- the 1st Exemplary Print Shop and the 20th Print Shop (Krasnii Proletarii)-- were both leased to Gosizdat publishing. Throughout the history of the USSR, government trusts led the printing industry in terms of ownership, but efforts to consolidate the industry (as a whole) remained disjointed.
The State Publishing House had its origins in Imperial Russia as the Royal Print Yard in St. Petersburg. As the Red Army controlled more provinces and cities in former Imperial Russia, the State Publishing House developed offices outside St. Petersburg. Irkutsk is a major city in southeastern Russia.
