In January 2007 the Director general of The Royal Library in Copenhagen, Erland Kolding Nielsen turned 60. "Umisteligt" is the festschrift released to mark the occasion. Erland Kolding Nielsen is known for his active participation in the public debate about the protection and preservation of the cultural heritage and the necessity of international co-operation in these matters. He was also instrumental in the planning and building of the Royal Library's new building, known as The Black Diamond. The 35 articles in this book have a wide range: From the Bronze-Age to the Internet, from Peru to Nizhny Novgorod, from Don Quil to the Danish treasury of song, from the worship of saints to the Kulturkampf. However they all have the same point of interception: the manifold Danish cultural heritage and the management of it through time.
