Calendars provide summaries full enough, for most purposes, to replace the original documents. These summaries are printed in chronological order and do not necessarily reflect the archival ordering of the documents (hence ‘calendar’). They are the primary finding aid for the records that they describe. The State Papers Simancas are papers relating to British diplomacy held in the archives of Simancas (Valladolid, Spain). This series covers the period 1558-1603.
