Great Soviet Encyclopedia
The third version was translated and submitted into English in 31 books between 1974 and 1983 by Macmillan Publishers. Each book was translated separately, making use of the index found at the front of each book to locate specific items; knowledge of Russian can be helpful to find the right book the first time. Not all versions were translated into English; these are indicated in the index. Articles from the English version are made available online by TheFreeDictionary.com.
