The article is devoted to the topic of scientific publication of memoirs of the participants of the All-Russian Local Council of 1917-1918. The publication of the diaries and notebooks of Archpriest Leonid Turkevich, the future Metropolitan of All America and Canada Leontius, the First Hierarch of the North American Metropolis in 1950-1965, the originals of which are kept in the Library of Congress, is considered. The diaries reflect the dramatic period of 1917-1918, when, as rector of St. Nicholas Cathedral in New York City, Archpriest Leonid participated in the work of the 1917-1918 Council as a representative of the North American Diocese-Mission. Archpriest Leonid kept records of the discussions and various messages of the participants of the Council, noted interesting details of behind-the-scenes discussions, and left us his impressions of Russia, which appeared as if in a new light after a long stay abroad. The publishers of these sources are candidate of theology, priest Evgeny Ageyev and candidate of historical sciences A.I. Mramornov.
