York, both as the leading city in the North of England and from its ecclesiastical importance, was from very early times an important centre of book production. The text writers and illuminators of manuscripts had formed themselves into a guild as early as the time of Edward III., while the bookbinders became a separate company in 1476. Like most of the leading provincial towns, York was very jealous of its privileges and made stringent regulations as regards its trade and business. In 1488 the various crafts connected with books passed a bye-law enacting that no person, secular or religious, not franchised or allowed by the craft, should bring in or set out any work. Poor priests were allowed to augment their salaries by the practice of text writing and illumination, and any priest might write and illuminate books provided they were for his own use, or to be given away in charity. York books may be divided into three groups. 1. Those actually printed in York. 2. Those printed elsewhere but containing a York stationer’s name. 3. Those printed elsewhere, without a stationer’s name, but obviously intended for sale in the city. The earliest book connected with York belongs to the last group. It is a _Breviary_ for York use, and was printed at Venice by a well-known printer of such books, Johann Hamman or Hertzog of Landau in 1493, at the costs of Frederick Egmont, an English bookseller. The book is a beautifully printed octavo of 478 leaves, printed in double columns in red and black. One copy only is known, now in the Bodleian. It belonged at one time to Ralph Thoresby, the Yorkshire antiquary, then to Marmaduke Fothergill, whose widow presented his library to the Dean and Chapter of York in 1731. This volume, however, did not reach the Minster library, but passed into the collection of Edward Jacob, the antiquary, who died in 1788. At his sale it was bought by Richard Gough. Gough in his will bequeathed his topographical collections to the Bodleian, and English service books being connected with the uses of Salisbury, York, and Hereford were fortunately classed as topography. By this means the liturgical collections of the Bodleian were increased with thirty-nine _Missals_, twenty-one _Breviaries_, twenty-five _Horæ_ and twenty-one _Manuals_ and _Processionals_ besides _Psalters_, _Hymnals_, _Graduals_, and other books. This _Breviary_ is the only book printed for York in the fifteenth century, yet though text writing seems to have flourished well up to 1500, the importation of printed books soon showed the advantage of printing over writing, and the stationers began to commission service books.
