Cooperation B.V. Klyuchevsky with S.F. Platonov on the distribution of his father's work

Much of S.F. Platonov's organizational work remains unknown. The revealed archival materials in his personal fund allow us to expand our understanding of his personal interest in providing the students of the Women's Pedagogical Institute, where he was the director, with the best scientific literature. The director's hand-drawn rough sketches provide an insight into the extent of his collaboration and informal relationships with his female students. The office materials introduced into scientific circulation for the first time give an idea of the unknown side of the activity of B.V. Klyuchevsky - the son of the great historian. In historiography, the opinion has been established that he mainly performed the duties of secretary to his father. The researchers ' interest in the tragic fate of the only child of V.O. Klyuchevsky began to manifest itself recently. He was not spared the fate of a prisoner exiled to Kazakhstan. Previously unknown, his work in the warehouse of V.O. Klyuchevsky's printed products allows him to open a new page of his studies. Despite a certain dryness of office materials (receipts of postal orders, forms, invoices), they in this case allow us to analyze the functioning of the warehouse for the distribution of V.O. Klyuchevsky's works, to find out the scale of trade. Some inaccuracies established in historiography concerning the facts from the life of S.F. Platonov and B.V. Klyuchevsky are corrected
