The records of the medieval English courts were compiled into manuscript ‘year books’, organised by regnal year of the monarch, and further subdivided into the four law terms. The year books of the reign of Edward III (1312-77), beginning at the eleventh year (1337) and continuing to the twentieth (1346), were to have been edited for the Rolls Series by Alfred Horwood (1821-81), who had previously edited the year books of Edward I, but he died while the first volume was in proof. The work was taken over by L. O. Pike (1835-1915), the set of fifteen books being published between 1883 and 1911. (Horwood chose his start date because the year books of Edward II and the first part of the reign of Edward III already existed in modern editions.) This volume contains reports from Hilary Term, 11 Edward III, to Trinity Term, 12 Edward III.
