From the earliest times certain books, mainly on medicine, were collected at the Hotel Dieu, the great hospital of Paris, and this collection was added to from time to time by the bequests of physicians in attendance there. This was doubtless the first regular hospital library, though probably medical books had also been collected at Salernum. The principal colleges of the universities also made collections of books, some of them {153} very valuable, though as a rule, it would seem as if no attempt was made to procure any other books than those which were absolutely needed for consultation by the students. The best working library at Paris was undoubtedly that of the Sorbonne, of which indeed its books were for a long time its only treasures. For at first the Sorbonne was nothing but a teaching institution which only required rooms for its lectures, and usually obtained these either from the university authorities or from the Canons of the Cathedral and possessed no property except its library. From the very beginning the professors bequeathed whatever books they had collected to its library and this became a custom. It is easy to understand that within a very short time the library became one of the very best in Europe. While most of the other libraries were devoted mainly to sacred literature, the Sorbonne came to possess a large number of works of profane literature. Interesting details with regard to this library of the Sorbonne and its precious treasures have been given by M. Leopold Delisle, in the second volume of Le Cabinet des Manuserits, describing the MSS. of the Bibliothèque Nationale at Paris. According to M. Lecoy de la Marche, this gives an excellent idea of the persevering efforts which must have been required, to bring together so many bibliographic treasures at a time when books were such a rarity, and consequently enables us better almost than anything else, to appreciate the enthusiasm of the scholars of these early times and their wonderful efforts to make the acquisition of knowledge easier, not only for their own but for succeeding generations. When we recall that the library of the Sorbonne was, during the Thirteenth Century, open not only to the professors and students of the Sorbonne itself, but also to those interested in books and in literature who might come from elsewhere, provided they were properly accredited, we can realize to the full the thorough liberality of spirit of these early scholars. Usually we are prone to consider that this liberality of spirit, even in educational matters, came much later into the world.
