The article analyzes the source-based research base of the composer’s work in the genre of sacred choral music of one of the most famous composers of the “Przemysl school” — Ivan Andriyovych Lavrivskyi (1823–1873). It was noted that in the funds of the Lviv Scientific Library of Ukraine named after V. Stefanyk preserves a whole set of source materials, primarily sheet music manuscripts and prints of spiritual choirs of the composer. The amount of sheet music materials, chronological framework, presence of autographs, ways of origin and arrival to the fund collection were established and clarified.
