The libraries themselves, moreover, are of surpassing interest because of their rules and management, for little as it might be expected this wonderful century anticipated in these matters most of our very modern library regulations. The bookmen of the time not only made beautiful books, but they made every provision to secure their free circulation and to make them available to as many people as was consonant with proper care of the books and the true purposes of libraries. This is a chapter of Thirteenth Century history more ignored perhaps than any other, but which deserves to be known and will appeal to our century more perhaps than to any intervening period.
The constitutions of the Abbey St. Victor of Paris give us an excellent idea at once of the solicitude with which the books were guarded, yet also of the careful effort that was made to render them useful to as many persons as possible. One of the most important rules at St. Victor was that the librarian should know the contents of every volume in the library, in order to be able to direct those who might wish to consult the books in their selection, and while thus sparing the books unnecessary handling also save the readers precious time. We are apt to think that it is only in very modern times that this training of librarians to know their books so as to be of help to the readers was insisted on. Here, however, we find it in full force seven centuries ago. It would be much more difficult in the present day to know all the books confided to his care, but some of the { 151} librarians at St. Victor were noted for the perfection of their knowledge in this regard and were often consulted by those who were interested in various subjects.
In his book on the Thirteenth Century [Footnote 15 ] M. A. Lecoy de la Marche says that in France, at least, circulating libraries were quite common. As might be expected of the people of so practical a century, it was they who first established the rule that a book might be taken out provided its value were deposited by the borrower. Such lending libraries were to be found at the Sorbonne, at St. Germain des Prés, as well as at Notre Dame. There was also a famous library at this time at Corbie but practically every one of the large abbeys had a library from which books could be obtained. Certain of the castles of the nobility, as for instance that of La Ferte en Ponthieu, had libraries, with regard to which there is a record, that the librarian had the custom of lending certain volumes, provided the person was known to him and assumed responsibility for the book.
