The virtual exhibition Første Verdenskrig 1914-1918 [First World War 1914-1918] has been created by Det Kongelige Bibliotek in Copenhagen, the Danish national library. This virtual exhibition has been launched to accompany the exhibition Ned med våbnene [Away with weapons] at Det Kongelige Bibliotek (September 4, 2014-January 31, 2015). The focus of the virtual exhibition is on seven very different persons: a politician, a soldier, a woman active in the peace movement, an interpreter working with prisoners of war, a union leader, a socialist and an intellectual. Each of them is briefly portrayed, and you can look at telling images or listen to spoken versions of some of their writings. This virtual exhibition can only be viewed in Danish.
