William Reade was a medieval Bishop of Chichester. Reade was brought up, from boyhood to maturity, by his friend and protégé Nicholas of Sandwich. He was then educated at Exeter College, Oxford and elected from it to a fellowship at Merton College, Oxford where astronomy, mathematics and natural philosophy flourished. He collected what was probably the largest private library in 14th-century England, and was one of the University's greatest benefactors. Reade wished to provide resources for Oxford scholars as there was no University library at the time, Reade donated and bequeathed some 350 volumes to the libraries at Merton, Exeter, Balliol, Oriel, Queen's, and New Colleges, Oxford. Reade also provided a large sum of money to support the building of the library that is still in use today. In 1365 Reade was made provost of the college of Wingham, Kent, and archdeacon of Rochester in 1369. He was nominated for Bishop of Chichester on 23 September 1368, and by provision of Pope Urban V was appointed to the see of Chichester on 2 September 1369. Reade's contribution to Chichester Cathedral was the systematic compilation of cartularies, gathering together all the charters and writings concerning the church. His cartularies have preserved virtually the only early documentary evidence about the Cathedral. Reade converted the old Manor House at Amberley, into a castle. Stephens says he did this to provide a strong fortress for himself and his successors against troublous times. Reade held a deer park, in Selsey, that was plagued with poachers so much so, that the incensed bishop issued a decree excommunicating the offenders by "Bell, book, and candle", and he ordered that the ritual should be performed at all churches within the deanery. Reade died 18 August 1385, and asked in his will to be buried at Selsey parish church then located at Church Norton before the high altar. His wish was not acted upon as he was buried in Chichester Cathedral without monument. It seems that this was not the only problem with the execution of his will as the dean and chapter, of Chichester Cathedral, petitioned the executors, thirteen years later, to account for the thirteen gilt cups, bequeathed by Reade, for the use of the cathedral.
