This small collection consists of correspondence, a short typescript biography of T︠S︡itron by an unidentified author, and clippings of articles by T︠S︡itron in emigre Russian newpapers. Correspondence includes one letter each by Mark Aldanov and Oskar Gruzenberg, and nine by Vasiliĭ Maklakov.

The Ob"edinenie Russkikh Advokatov Vo Frantsii Records (Union of Russian Lawyers in France Records) contain correspondence, manuscripts, minutes and reports of meetings, subject files, and printed materials. Founded in 1926, the Union's first president was Nikolaĭ Teslenko, who was succeeded by Boris Gershun. From the early 1950s on the Union's activities became increasingly sporadic; its last general meeting was apparently held in 1973. The papers mostly concern 1930-1960. Cataloged correspondents are Oskar Gruzenberg, Maksim Vinaver, and Vasiliĭ Maklakov. There are annual reports of the Union's activities, and files on meetings of its executive council and on general meetings. Also included are membership lists and notes on members. Subject files concern chiefly Union activities. Substantial biographical materials on emigre lawyers can be found in the files related to the "Memorial of the Russian Legal Profession in the Emigration.".
