Publishing houses in the Soviet Union

Publishing houses in the Soviet Union, were a series of publishing enterprises which existed in the Soviet Union.
Centralization.
On August 8, 1930 the Sovnarkom of the Russian Soviet Federative Socialist Republic (RSFSR) established the state publishing monopoly, OGIZ (ОГИЗ, Объединение государственных книжно-журнальных издательств, Union of the State Book and Magazine Publishers), subordinated to Sovnarkom. At its core was the former Gosizdat. Other union republics followed the same pattern.
During the era of centralization the names of the most publishers contained the acronym "гиз" ("giz") standing for "государственное издательство" ("gosudarstvennoye izdatelstvo", i.e., "State Publisher", S.P.).
