The steadily growing archives collection contains at this moment nearly 600 archives of Dutch composers, performing musicians and musical institutions. Included are more than 45.000 music manuscripts mainly of Dutch composers, more than 200.000 letters, thousands of photographs, personal documents (diplomas, testimonials, diaries etc.) and audio and video materials.

Represented are such highly prominent musicians as conductor Willem Mengelberg and composers Julius Röntgen, Hendrik Andriessen, Tristan Keuris and Peter Schat. Also there are archives of institutions like the Royal Society for Music History of The Netherlands (KVNM), The Society of Dutch Composers (Geneco) and Donemus. This major source for Dutch musical historiography stretches over more than 1700 m and is still growing. It is supplemented by the large documentation collection and by literature in the library.

Most archives have been described in inventories on paper which can be consulted locally. A small but growing number of inventories is made available in digital format on this website.

Audio recordings in the NMI archives are mainly of Dutch music and/or musicians. These include gramophone records, broadcast transcription records, magnetic tapes and digital recordings. Many of these materials are part of the legacies of Dutch musicians and are unique items. An example of special importance is the so-called Hardie Collection of 78 rpm gramophone recordings of conductor Willem Mengelberg. At this moment access to the audio materials is limited.
