Extensive legacy of Julije Njikoš (Osijek, 1924 – Zagreb, 2010), doyen of Croatian tambura music, is preserved at the Museum of Slavonia. According to his wishes, it was gifted to the museum in 2012 ...by his wife Vera Svoboda and daughters Vesna Njikoš Pečkaj and Mirna Njikoš Pavlović. The legacy consists of sheet music, sound recordings, and private belongings (photos, concert programmes, wards, newspaper articles). This paper is dedicated to sheet music from the legacy of Njikoš, which was inventoried and scanned, and professionally processed during 2021. More than eight hundred of sheet music is divided into four categories: original compositions of Njikoš; recordings and covers of folk songs and dances for tambura orchestras; compositions of other authors that were arranged by Njikoš for tambura orchestras; compositions of unknown status in relation to Njikoš. This paper brings out their overview on the basis of their processing and consultations with professional literature, sheet music collections in which they were published, and sound recordings on which they were recorded. On one side, these musical sources are a witness of creative productivity of Njikoš, his efforts on preservation of national heritage and dedication to tambura playing in the widest sense, and on the other side, they provide us with the possibility for a wider contextualization of his life and work, as well as for further research of tambura music in Croatia.
