The book "Antarctic Rubicon" by Aleksandr Ovlashchenko offers an in-depth analysis of the development of Soviet historiography in the context of Antarctic research. It examines the internal mechanisms that shaped the historiographical process in the Soviet Union, focusing on a specific period from 1950 to 1954. This monograph is a continuation of the author's previous work, which dealt with the first Russian Antarctic expedition and its reflection in Soviet historiography. By comparing the two works, a more comprehensive understanding of the historical narratives and their development in the history of Soviet science is achieved. The book is significant for both professionals and those interested in the history of Antarctica and Soviet historiography.
