Moreover, all the books of the College are to be kept in some safe room, to be assigned for the College Library, so that all the Scholars of the College may have common access to them. We give leave, however, that the poor scholars of the college may have the loan of books containing the texts of Canon and Civil Law for their private use for a certain time, to be fixed at the discretion of the Master and the three Senior Fellows, provided they be not taken out of College; but the books of the Doctors of Civil and Canon Law are to remain continuously in the said Library Chamber, fastened with iron chains for the common use of the Fellows[268]. It is evident that this statute was regarded as a full and satisfactory expression of what was required, for it is repeated, with additions or omissions to suit the taste of the respective founders, in the statutes of New College (1400), All Souls' (1443), Magdalen (1479), Corpus Christi (1517), Brasenose (1521), Cardinal College (1527) and S. John's College (1555), at Oxford; and in those of King's College, Cambridge. Among these changes a few are sufficiently important to require special notice. At New College William of Wykeham allows students in civil law and canon law to keep two text-books "for their own special use during the whole time they devote themselves to those faculties in our College, provided they do not possess such books of their own"; the "remaining text-books, should any be left over, and also the glosses or commentaries of the Doctors of civil and canon law, may be lent to the persons belonging to those faculties by the method of annual selection, as in the other faculties"; the "books which remain unassigned after the Fellows have made their selection are to be fastened with iron chains, and remain in the Common Library for the use of the Fellows[269]"; the wishes of donors, whether expressed by will or during their lifetime, are to be respected; and, lastly, the safety of the Library is to be secured by three locks, two large, and one small, of the kind called "a clickett." The keys of the two former are to be kept by the Senior Dean and the Bursar respectively; of the clickett each Fellow is to have a separate key. At night the door is to be carefully locked with all three keys[270].
