Diplomatarium Danicum is an ongoing publishing project funded by Carlsberg Foundation (Carlsbergfondet). The principal aim of the project is to publish medieval charters (diplomas) from Denmark as well as letters from outside Denmark that refers to Danish affairs.
The records are written mainly in Latin, Low German and Danish, with Danish becoming more widely used around the beginning of the fifteenth century. The material is nowadays housed in archives throughout Europe; however, the majority of it can be found in the Danish National Archives (Rigsarkivet) in Copenhagen.
