One of the Vigeland Museum's core tasks is to facilitate research of Gustav Vigeland's art. This shows the museum through exhibitions and publications. For the museum, it is essential to have different views and angles to Vigeland's artistic work that stretched over a period of almost 50 years. The Vigeland Museum's archive contains approx. 20,000 letters, Vigeland's notebooks, photo collection, etc. This food is available for researchers by appointment.
