From your intro:
and the beginnings of the Cold War could be seen in cryptos, microdots, and the Gulag.
The last word (Gulag) is underlined instead of ital. And speaking of Gulag, it can be significantly antedated; I’ve found it in Russia in Chains; A Record of Unspeakable Suffering, Vol. 2 (Williams and Norgate Ltd., 1938); there are seven occurrences, e.g., p. 101: “Try to get a contract from the GULAG for a book. Call it something like this: ‘A Handbook of Physical Culture for the Labour-Correctional Camps.’ I will write it and we will split the fee. All right?” And in The White Sea Canal. Being an Account of the Construction of the New Canal between the White Sea and the Baltic Sea, by Maksim Gorky, Leopold Auerbach, et al., translated by Amabel Williams-Ellis (John Lane, 1935), again with seven occurrences, e.g., p. 244: “a new group of Gulag workers had arrived.”
