When the Bishop died some of his books went back to Durham; but the monks were generous towards the hall, and on several occasions sent fresh supplies to Oxford. It may also be observed that some of his best MSS. were returned to the Abbey of St. Alban's. He had bought about thirty volumes from a former abbot for fifty pounds weight of silver; but the monks had continually protested against a transaction which they believed to be illegal, and on Richard's death some of the books were given back, and others were purchased by Abbot Wentmore from his executors. De Bury's generous care for learning was imitated in several quarters. A few years after his death the Lady Elizabeth de Burgh made a bequest of a small but very costly library to her College of Clare Hall at Cambridge. Guy Earl of Warwick about the same time gave a collection of illuminated romances to the monks of Bordesley. John de Newton in the next generation divided his collection of classics, histories, and service-books, between St. Peter's College at Cambridge and the Minster at York, where he had acted for some years as treasurer. The lending-library at Durham Hall was the only provision for the public, with the exception of a few volumes kept in the 'chest with four keys' at St. Mary's. Thomas Cobham, Bishop of Worcester, had long been anxious to show his filial love for the University: as early as the year 1320 he had begun to prepare a room for a library 'over the old congregation-house in the north churchyard of St. Mary's'; and, though the work was left incomplete, he gave all his books by will to be placed at the disposal of the whole body of scholars. Owing to disputes that arose between the University and the College to which Cobham had belonged, the gift did not take effect until 1367. The University Library was established in the upper room, which was used as a Convocation House in later times; it is said not to have been completely furnished until the year 1409, more than eighty years after the date of the Bishop's benefaction. According to the first statute for the regulation of Cobham's Library, the best of the books were to be sold so as to raise a sum of L40, which according to the current rate of interest would produce a yearly income of L3 for the librarian; the other books, together with those from the University Chest, were to be chained to the desks for the general use of the students. It was soon found necessary to exclude the 'noisy rabble': and permission to work in the library was restricted to graduates of eight years' standing. Richard de Bury had warned the world in his chapter upon the handling of books, how hardly could a raw youth be made to take care of a manuscript; the student, according to the great bibliophile, would treat a book as roughly as if it were a pair of shoes, would stick in straws to keep his place, or stuff it with violets and rose-leaves, and would very likely eat fruit or cheese over one page and set a cup of ale on the other.
