Calendar of the Manuscripts of the Most Honourable the Marquess of Salisbury ... Preserved At Hatfield House, Hertfordshire ..

s "The series of these most important political and other documents commences in 1306, but papers of earlier date than the reign of Elizabeth are comparatively few. For the reigns of Elizabeth and James I, however,they constitute a body of state papers illustrative of general events and political transactions, with which the state papers preserved in the Public Record Office are alone comparable."--Roberts, R.
