The Leningrad branch of the Oriental Institute of the Academy of Sciences of the U.S.S.R. possesses a collection of nearly 150 Sogdian fragments recovered from various sites in Central Asia between 1893 and 1915. During the first three decades of this century a few texts were published by F. Rosenberg and C. Salemann. Thereafter the collection was for a long time ignored, while Russian Sogdianists turned their attention to the important archive of Sogdian documents discovered in 1933 at Mt. Mugh in Tajikistan. Everyone concerned with the languages and culture of medieval Central Asia will be deeply grateful to A. N. Ragoza, whose efforts have finally resulted in the complete publication of these interesting fragments. Her edition, reviewed here, includes texts, translations, commentary, glossary, and 69 pages of facsimiles.
