The demand for printed books in England, a demand which had, as we have seen, antedated the establishment of Caxton’s Press at Westminster, was much greater than could be satisfied by either Caxton, or his immediate successors, De Worde and Richard Pynson, and the importation of books from Paris, Rouen, Bruges, Antwerp, Cologne, and other continental cities, increased steadily during the last part of the fifteenth and the first portion of the sixteenth century. Of a number of the English publications of this period, the editions were printed on the Continent especially for the English market. Humphreys cites, among other instances, a series of missals printed in 1516 by Olivier of Rouen for the church of York, and an edition of the _Chronicles of England_ printed (in English) in Antwerp, in 1493, by Gerard Leew.[59] These Rouen missals were among the last of the Roman Catholic books of service printed abroad for the use of the English churches, as, in 1534, these churches adopted the _Ritual of the Reformation_. The title of the chronicles reads, “_Chronycles of the Lond of Englond_.” =Printing in Oxford.=--The second printing-office established in England was that of Oxford. The authority on the earlier history of printing in Oxford is the treatise and comprehensive bibliography of Mr. Madan, published in 1895, under the title of _The Early Oxford Press_. Some of the earlier historians of the University had claimed for the Oxford Press an earlier date than that of Caxton’s undertaking. This claim has rested almost entirely on the date 1468, which appears in the colophon of a treatise on the Apostles’ Creed, which treatise, says Madan, was undoubtedly the first product of the Oxford Press. The authorship of the volume as printed is ascribed to S. Jerome, and it is so referred to by Humphreys and other writers. Madan points out, however, that the actual author was Tyranneus Rufinus. It is his conclusion that the date 1468 (which is nine years earlier than the date of the first Caxton publication) is undoubtedly an error, and an error probably due to a single misprint.
