The collection includes cataloged photographs (Nicholas II, Grigoriĭ Semenov) and arranged correspondence to both Semchevskiĭ and his wife. The main item in the collection is Semchevskiĭ's eight-part memoir which describes his childhood in Tbilisi, his service as kamer-pazh (page of the bedchamber) to Nicholas II and his military career in World War I and the Civil War. It also describes Semchevskiĭ's life as an emigre in Berlin, where he ran a bookstore, in England, where he manufactured motorcycles, in Austria, where he worked at an oil refinery, and eventually in the United States. There are also documents (such as military records and passports) and a photograph of Semchevskiĭ and his wife taken in 1921.
