In the 1920s, the activities of the Buryat Scientific Committee were multifunctional. In addition to scientific researches, the committee carried on educational, publishing and translation activities, including the dissemination of communist ideas.

Organization of cooperation with leading scientific and educational structures of Russia has become a priority in the work of the Committee. By 1928, contacts have been established with over 40 institutions. The largest libraries, research institutes, publishing houses of central scientific journals were among them, for example, with the library of the Asian Museum of the Academy of Sciences, the Leningrad Institute of Living Oriental Languages, the Scientific Association of Oriental Studies, the Central Bureau of Regional Studies, the Kazan University, the Institute for the Study of Languages and Ethnic Cultures of Eastern Peoples, etc. In addition, contacts were established with famous Russian orientalists: A. V. Burdukovsky, B. Ya. Vladimirtsov, V. A. Kazakevich, N. K. Klyukin, S. F. Oldenburg, N. N. Poppe. Book exchange, including international, was established. It was the first channel of acquisition of the Committee’s library, including the distribution of scientific literature. The transfer of bibliographic values from the leading cultural, scientific and educational institutions of the country was the second channel for replenishing the Committee’s library. The acquisition of rare scientific oriental publications in bookstores in Moscow and Leningrad was the third channel. Collecting the items of scientific, cultural and historical value in the regions of Buryatia was the fourth channel of the Committee’s collections. The donating was the fifth channel. For example, D.
