But first let me mention that the principle of lending books to students under a pledge was accepted by the University of Oxford many years before colleges were founded. It is recorded that Roger L'Isle, Dean of York, in the early part of the thirteenth century, "bestowed several exemplars of the holy Bible to be used by the Scholars of Oxford under a pledge"; that the said books, with others, were "locked up in chests, or chained upon desks in S. Mary's Chancel and Church to be used by the Masters upon leave first obtained"; that certain officers were appointed to keep the keys of these chests, and to receive the pledges from those that borrowed the books; and that the books were so kept "till the library over the Congregation House was built, and then being taken out, were set up in pews or studies digested according to Faculties, chained, and had a keeper appointed over them[259]." In the statutes of Merton College, Oxford, 1274, the teacher of grammar (_grammaticus_) is to be supplied with a sufficient number of books out of the funds of the House, but no other mention of books occurs therein[260]. The explanatory ordinances, however, given in 1276 by Robert Kilwardby (Archbishop of Canterbury 1273-79), direct that the books of the community are to be kept under three locks, and to be assigned by the warden and sub-warden to the use of the Fellows under sufficient pledge[261]. In the second statutes of University College (1292), it is provided, "that no Fellow shall alienate, sell, pawn, hire, lett, or grant, any House, Rent, Money, Book, or other Thing, without the Consent of all the Fellows"; and further, with special reference to the Library: Every Book of the House, now given, or hereafter to be given, shall have a high value set upon it when it is borrowed, in order that he that has it may be more fearful lest he lose it; and let it be lent by an Indenture, whereof one part is to be kept in the common Chest, and the other with him that has the Book: And let no Book, belonging to the House, be lent out of the College, without a Pawn better (than the Book), and this with the Consent of all the Fellows. Let there be put one Book of every Sort that the House has, in some common and secure Place; that the Fellows, and others with the Consent of a Fellow, may for the Future have the Benefit of it. Every Opponent in Theology, or Reader of the Sentences, or a Regent that commonly reads (_regens et legens communiter_), when he wants it, shall have any necessary Book, that the House has, lent to him Gratis; and when he has done with it, let him restore it to that Fellow, who had formerly made choice of it[262]. The statutes of Oriel College, dated 1329, lay down the following rules for the management of books:
