The book is devoted to the bibliographical reconstruction and study of the court library of the Qongrat dynasty of Khorezm. Confiscated as a war trophy during the conquest of the Khanate of Khiva by Russian troops in 1873, the library was taken to the Russian Empire's capital, St Petersburg. The book consists of two parts: the first part discusses the nature and functioning of this court library, the political, social, and cultural background for the development of literature and book culture in the Khanate, the circumstances of the removal of manuscripts from Khiva and their subsequent transfer to Russian academic institutions, as well as methodological aspects of reconstructing the library. The second part contains descriptions of manuscripts identified as originating from this library.
