Secondly, by the time that Lanfranc was writing his statutes for English Benedictines, it was evidently contemplated that the number of books would have exceeded the number of brethren, for the keeper of the books is directed to bring all the books of the House into Chapter, and after that the brethren, one by one, are to bring in the books which they have borrowed[146]. Among the books belonging to the House there were probably some service-books; but, from the language used, it appears to me that we may fairly conclude that by the end of the eleventh century Benedictine Houses had two sets of books: (1) those which were distributed among the brethren; (2) those which were kept in some safe place, as part of the possessions of the House: or, to adopt modern phrases, that they had a lending library and a library of reference. Thirdly, it is evident that the loan of books to persons in general, on adequate security, began at a very early date. On this account I have already ventured to call monastic libraries the public libraries of the Middle Ages. As time went on, the practice was developed, and at last became general. It was even enjoined upon monks as a duty by their ecclesiastical superiors. In 1212 a Council which met at Paris made the following decree, but I am not able to say whether it was accepted out of France: We forbid those who belong to a religious Order, to formulate any vow against lending their books to those who are in need of them; seeing that to lend is enumerated among the principal works of mercy. After careful consideration, let some books be kept in the House for the use of brethren; others, according to the decision of the abbat, be lent to those who are in need of them, the rights of the House being safe-guarded. From the present date no book is to be retained under pain of incurring a curse [for its alienation], and we declare all such curses to be of no effect[147]. In the same century many volumes were bequeathed to the Augustinian House of S. Victor, Paris, on the express condition that they should be so lent[148]. It is almost needless to add that one abbey was continually lending to another, either for reading or for copying[149]. Houses which lent liberally would probably be the first to relax discipline so far as to admit strangers to their libraries; and in the sixteenth and following centuries the libraries of the Benedictine House of S. Germain des Pres, Paris, as well as the already mentioned House of S. Victor, were open to all comers on certain days in the week.
