The Johanna Spyri and Heidi archives in Zurich have been added to UNESCO's Memory of the World International Register. The decision by the Executive Board of UNESCO acknowledges the collections' universal importance. The University of Zurich will be working with both institutions to promote the academic study of the collections.
