Significant part of the US Library of Congress collections is associated with the history of the St. Petersburg Ballet, and participation of its soloists in tours around the cities of Europe and the United States of America. The funds contain not only monographs, brochures, newspapers, which reflect the history of the St. Petersburg Ballet, but also rare scores, memoirs of ballet soloists and organizers of their tours. There are also unique photographs and audio recordings in the Library.
