PSOc1327-1884Records of the Keeper of the Privy Seal
Records of the Privy Seal Office relating to responsibilities for validating instruments issued by the royal administration, and later the government.
Warrants for the privy seal are in three series: PSO 1, Edward III to Henry VIII; PSO 2, Henry VII to Charles II; and PSO 3, 1766 to 1851. The first two especially are very incomplete, being mainly made up from records found in the Treasury of the Receipt of the Exchequer and the Pells Office. The Privy Seal Docquet Books in PSO 5 and their indices in PSO 6 provide a means of reference from 1571 to 1884.
A collection of miscellaneous later records of the office is in PSO 4 and original finding aids to the Privy Seal records are in PSO 7
