The documentation collection consists of a large number of historical concert programmes, cuttings, magazine articles, folders and flyers documenting musical life in the Netherlands.

The collection of some 50.000 concert programmes from the 19th and 20th Centuries is an important aid in gaining an insight in the history of musical performance in the Netherlands. Besides the major orchestras, it includes church, organ, choir and chamber music. The programmes of Diligentia concert hall in The Hague, for instance, have been preserved since 1821.
