Roger Bacon’s reference to the scribes of Paris has already been mentioned. He could not secure from the Brothers of his Order a transcript of his work which he desired to present to Pope Clement, because they were too ignorant to write the same out intelligently, while he was afraid to confide the work to the public scribes of France lest they might make improper use of the material.[302] It is Wattenbach’s opinion that the wrongful use of his production dreaded by Bacon was the sale of unauthorised copies of it by the scribes to whom the preparation of the authorised copies should be confided. In 1292, Wenzel, King of Bohemia, presented to the monastery of Königsaal, 200 marks in silver for the purchase of books, and the purchases were made from the book-sellers in Paris. Richard de Bury extols Paris as the great centre of the book-trade. Of the value of the book collections in Rome and the possibility there of securing literary treasures, he had already spoken, but the treasures of Paris appear to have impressed him still more keenly. There he found occasion to open his purse freely and took in exchange for base gold, books of inestimable value. Joh. Gerson, in his treatise _De Laude Scriptorum_ expresses the dread lest the persistent carrying away from Florence of his books by wealthy visitors may not too seriously diminish its literary treasures. The Paris publishers appear to have sent out travelling salesmen or representatives to take orders for their wares. As early as 1480, a publisher named Guillaume Tousé, of Paris, made complaint to the chancellor of Brittany to the effect that he had entrusted a commission to a certain Guillaume de l’Espine to carry books into Lower Brittany and to make sale of the same during a period of six months. He had taken with him books to the value of five hundred livres and was to have a salary of ten crowns for the six months’ work. He had, however, failed to return or to make report of his commission. Tousé secured a judgment against his delinquent traveller, but the record does not show whether he ever succeeded in getting hold of him again.[303] In the universities of Oxford and of Cambridge, the _stationarii_ began their work some years later than in Paris or Bologna. They had the advantage, however, of freedom from the greater portion of the restrictions and special supervision which hampered the work of the scribes in the Italian and French universities, and as a result their business developed more promptly and more actively, and in the course of a few years, they became the booksellers of the university towns. It was, of course, from this university term _stationarii_ that the name of stationers came at the outset to be applied to the organised book-dealers of Great Britain. The Guild of the British book-dealers completed its organisation in 1403, nearly sixty years before the introduction into England of the printing-press.[304]
