The one which I was reading - edited in 1824 by Mr. Thompson, librarian to Sir Thomas Raleigh - sins, it is true, by excess of brevity, and does not offer that character of exactitude which the archivists of my own generation were the first to introduce into works upon diplomatics and paleography.

Pierre Chaplais secured a rightful place as his generation's doyen of the formulaic study of medieval English royal documents (known as diplomatics) by producing such works as Diplomatic Documents Preserved in the PRO, 1101–1272 (1964; rpt. 1976), Essays in Medieval Diplomacy and Administration (1981), and the ambitious two-volume reference manual English Medieval Diplomatic Practice (1975–1982).
