the oldest and longest series of English public records and a valuable source for the financial and administrative history of medieval England. Apart from an isolated survival from 1130, they begin in 1156 and continue with few breaks until 1832. Their name probably derives from the fact that the sheepskin rolls, when stored in their presses, resemble a stack of pipes.

The rolls contain the yearly accounts of the sheriffs, who were the chief financial officers for individual counties. The rolls sometimes also contained the accounts of other royal officials. Royal income from feudal dues, judicial fees, and other sources is balanced against the expenses of the crown's officers, providing a basis for the calculation of the king's revenue. As new accounting offices were set up to handle revenue, the Exchequer accounts diminished in importance. In 1883 a Pipe Roll Society was founded and began publishing all the rolls.
