Notes of hymns and folk songs collected and transcribed by the Karbelashvili brothers were published as an online collection on the website of the National Archives of the Ministry of Justice of Georgia.

The collection includes several dozen hymns and troparia. It includes autograph texts of the Karbelashvili brothers as well as notes transcribed by students of the theological seminary.

 The manuscript notes of the hymns are part of the valuable archival material that has been stored in the National Archives of Georgia, in the personal fonds of Polievktos Karbelashvili, since the 1940s.

The collection is available at the link: https://archive.gov.ge/ge/sagaloblebis-notebi-1.
