The foundation of the College of the Sorbonne dates from 1257. It was organised by Robert de Sorbon, chaplain to Louis IX. The college was at once affiliated with the University of Paris, of which it became the theological Faculty, and in the general direction of which it exercised at times a controlling influence. The college is connected with my subject on the ground of its assumption of the theological censorship of the Paris book-trade and of its frequent attempts to exercise a general censorship over all the productions of the Paris printing-press. As we shall note later in the history of the Paris book-trade, various complications arose between the publishers and booksellers possessing a university license (the _libraires jurés_) and certain unlicensed dealers who undertook to come into competition with them. The locality occupied by these unlicensed booksellers was on the Island of the Cité, immediately by the precincts of Notre Dame. In fact it was the case with the book-trade generally north of the Alps that its business was very largely carried on in the portals of a church if not under the immediate shadow of the cathedral. While in Italy the Church furthered but slightly the early production of books and, later, did not a little to hamper the undertakings of the publishers, it was the case in France and quite largely also in South Germany, that the publishers found themselves very largely dependent upon the scholarly interests and the scholarly co-operation of the clerics, and the association of the Church with the book-trade was, for a large proportion at least of the fifteenth century, an important one. In Paris, the booksellers licensed by the university were all in the Latin Quarter, and in the same region were to be found the sellers of parchment, the illuminators, the scribes, binders, etc., who also carried university licenses and were under university supervision. It is probable that the specification in the Tax Roll of 1292 of eight _librarii_ in Paris refers only to the booksellers licensed by the university and carrying on their business in the Latin Quarter. In Bayeux, in 1250, certain clerics were exempted from taxation if they dealt in parchment or if they were engaged in the copying of manuscripts, and the book-shops along the walls of the cathedral were also exempt from taxation. It is not clear to me in looking up this record, whether the tax mentioned was a town tax or a general tax, or whether it was one of the ecclesiastical levies.[301]
