Most of the documents in this series relate to aspects of the Privy Seal Office's work in passing instruments under the privy seal - translating a warrant under the signet or sign-manual into a writ of privy seal, which would authorise the use of the great seal by Chancery, or the issue of money by the Exchequer. Most of these records are concerned with the fees due to the clerks, and the costs of applying the seal. Included in this series are various account and fee books, journals, letters and odd items of office paperwork, circulars, etc.
