The Netherlands Music Institute (Nederlands Muziek Instituut, NMI) is the central institution for the preservation of the musical heritage of the Netherlands.
In that same year the NMI was designated ‘sector institute for musical heritage’ by the Ministry of Education, Culture and Science.
It receives a subsidy from the municipality of The Hague and from the national government.
Historical roots of the NMI are the music archives and music library of the Gemeentemuseum Den Haag (Municipal Museum) in The Hague and the documentary collection of the Musica Neerlandica Foundation.
Several major collections have been integrated into its holdings of sheet music; among them, that of the Théâtre Français de La Haye (700 scores with parts, printed before 1850), the Johann Alsbach collection of music published in the Netherlands (11.000 titles), the Frans Vester collection of flute music (4000 titles) and Willem Noske collection of violin music (27.000 titles).
