There are several institutions that advice and support professional artists at a professional level.
A lot of music is archived. The Dutch Institute for Image and Sound has the biggest archive in the Netherlands. Besides there are some smaller archives. Besides collecting and archiving, the institutions unlock and provide information for scientific research.
Professional associations and trade unions represent musicians interests and give them advice on their professional practice: juridical, fiscal and financial advice.
Knowledge organisations gather information and by doing that they generate knowledge to be spread in different ways. This can be about all sorts of subjects and genres. For example microtonal or classical music, promotion or copyright.
