Correspondence between Elkin, based in London, and prominent Russian emigrés discussing recent and contemporary politics and history, with particular emphasis on Russia since 1894. Very often, key publications on the subject are discussed, notably the P.N. Miliukov's Vospominania (memoirs). A friend and admirer of this statesman and liberal historian, Elkin in his editorial role offers constructive criticism. He also mentions, although without any detail, the role of Russian freemasonry in the October Revolution and beyond. The letters briefly touch Jewish issues. The last group of letters represent Elkin’s quest to recover records of interviews with Aleksander Ivanovich Guchkov (1862-1936).

In Russian Cyrillic, except 3 letters in the last group, which are in English. The groups follow the order of the earliest dates, in chronological order within each group. Apart from a handful of manuscript letters, these are predominantly typescript copies. At least three letters (from B. Elkin to M. Aldanov dated 24 May 1945, from B. Elkin to V. Maklakov dated 17 July 1948 and From V. Maklakov to B. Elkin dated 30 Mar. 1956) are incomplete. Comprises:
