The document discusses the future of music libraries and proposes strategies for the DOK Library Concept Center in Delft, Netherlands to remain relevant. It notes that the library's large music collection is unused as online access is easier. It proposes three strategies - a new digital strategy focused on streaming and curating accessible content (yellow line); introducing new types of content like streaming media and ways to experience instruments silently (red line); and engaging new patrons and cultural professionals to establish the library as the cultural center of Delft (blue line). The goal is to transition the library from a passive collection to an active experience where people can learn, play and discover music.
