In 2025, the Institute of History of the Siberian Branch of the Russian Academy of Sciences celebrates several significant dates associated with the formation and development of such branches of academic historical science in Siberia as source studies and archeography. The starting point for the anniversary dates should be 1965, with which two important events are inextricably linked: the first archaeological expeditions of employees of the Siberian Branch of the Academy of Sciences and Novosibirsk State University and the donation by Academician M.N. Tikhomirov to the Siberian Branch of the USSR Academy of Sciences of his remarkable collection of manuscripts, early printed books and historical documents. It was from that time, and for 60 years now, on a permanent basis and with regular frequency, almost every year, that archaeographic expeditions have been sent from the Novosibirsk Academic City on trips for rare books. In the first years, their sphere of interests covered a vast territory of the Trans-Urals, Siberia, the Far East and Central Asia. The result of this large-scale work was the discovery for science of many previously unknown ancient Russian and Old Believer written monuments, the most striking works of previously unknown literature of the Siberian peasantry. We can rightfully speak about the 60th anniversary of the archaeographic discovery of Siberia.
