SWEDEN  .—The archives have not yet been centralized, and large collections exist at the various ministries . The most important records, however, are the Royal Archives (Rigsarchivet), pre-served in the

island of Riddarholmen, Stockholm . A great many publications have been based on these: there are for instance an inventory, Middlelanden fran Svenska Rigsarchivet ; a work bearing generally on Scandinavian history, Handlingar rorande Scandinnaviens historia ; and the Diplomatarium Suecicum, which is still in progress . The English Record Office has seven volumes of transcripts from the Stockholm archives, with a report . Private collections are numerous and valuable, and a society for exploring and publishing such records is supported by the state .
