Andreevskii: his memoirs up to 1917; memoirs of a trip to Palestine in 1881; and his diary for 1919-1931. Also included is a typescript copy of the memoirs of historian Boris Chicherin, entitled "N.I. Krivtsov." Many of the printed materials concern the Orthodox Church in emigration.

Nearly all the manuscripts are by Unkovskiĭ, and include essays, stories, and excerpts from his memoirs, many of which were published in emigre journals. There are a number of scrapbooks containing clippings of his articles. In addition, the collection contains galleys of books by Unkovskiĭ, and copies of some of his full-length works, including "Ikary" (1942) and "Andreĭ Klinskiĭ" (1940).

The collection consists of correspondence, manuscripts, and an enormous number of notecards (that were collected over a twenty-year period for a proposed "Slovar' russkikh khudozhnikov") and several dozen notebooks containing entries to which the cards refer. Among the correspondents is Eugène Fabergé, whose letters contain information about the Fabergé dynasty of jewelers. Sakharov's manuscripts include essays on Ivan Bilibin, M. V. Rudaltsov, Mariia Bashkirtseva, Nikolai Globa and V. E. Borisov-Musatov. The cards containing information on artists are arranged alphabetically by artist and contain references to specific notebook entries. There are also bibliographic cards containing citations of articles on art in Russian and other languages. These are arranged by author. The notebooks are largely devoted to a particular artist or genre; others are designated by color and number, letter, number or not titled at all. There are also two sets of large notebooks which seem to belong to another series. There are a few photographs of artists (notably a 1939 photograph of Globa) and photographic reproductions of works by Bakst and Lukin among others. The collection contains approximately 11 exhibition catalogues dating from 1915 to 1940 and primarily relating to the exhibitions of Russian emigre artists in Paris. There are also 4 issues of "Illiustrirovannaia Rossiia" and some clippings dealing with Russian emigre artists.
