The article examines current issues in the development of archaeography in Siberia, focusing on identifying Siberian manuscripts and collections within Moscow monasteries in the 19 th and early 20 th centuries, their circulation, and collection formation. The integration of Siberian culture into the panRussian context was significantly influenced by the personality and policies of ruling bishops. In the second half of the 19 th century, this was Metropolitan Innocent (Veniaminov), who had Siberian origin and extensive service there. His activities as Metropolitan of Moscow facilitated the attraction of Siberian clergy to the capital, who brought their book and manuscript collections, which could be concentrated in specific Moscow Orthodox monasteries. The Pokrovsky Missionary Monastery, along with its affiliated Missionary Institute, could become a center for concentrating manuscripts and individual missionary artifacts. The article attempts to analyze the manuscript collection of Archpriest Fortunat Petukhov as a reflection of the institute's library formation. Using the manuscript collection of Archimandrite Philaret as an example, the article seeks to present the principles of collection formation, manuscript selection criteria, and raises the question of studying the activities of the institute's graduates in missions in Siberia, the Far East, and the Turkestan region. The institute's library, like its manuscript collection, requires research. The example of Moscow's Zlatoustovsky Monastery indicates that Siberian manuscripts could also enter monastic collections through donations from Siberian parishioners, thereby testifying to Siberian sacred sites (the life of St. Innocent of Irkutsk).
