The Great Soviet Encyclopedia (BSE) is a symbol of the Soviet era and one of the most prominent publications in the world. Established in 1926, it covers a wide range of knowledge from various fields of science, technology, art, history and culture. Each volume of the encyclopedia contains many articles, illustrations and maps that help the reader find answers to any questions. BSE was distinguished not only by the volume of information, but also by the detail and authority of the sources. Of great importance was the fact that each article was signed by scientists and specialists, which gave readers confidence in the reliability of the information. The Great Soviet Encyclopedia became not only a reference book, but also a symbol of ideology and scientific progress. It has become an important source of knowledge for a wide range of readers, from students to scientists. This encyclopedia has always served the desire for knowledge and culture, and remains an integral part of the history of the Soviet and post-Soviet space."
