[Illustration: Paper Sorting] [Illustration: Paper Stock Warehouse] Most varieties of high-class printing paper are made at Wolvercote, which besides feeding the Press does a considerable trade with other printers. The paper made for the Oxford Dictionary and some other books is of the finest rag and is probably as durable as the best hand-made paper of former times. But the Mill is best known for its ‘Bible’ papers, exceptionally thin, tough, and opaque, with a fine printing surface. Paper of this kind reaches its acme in the famous Oxford India Paper, the invention of which made revolutionary changes in the printing of Bibles. A great many Oxford books are now printed in two editions, an ordinary and an India paper. If the saving of space is an important consideration, the convenience of the thinner editions of such books as the _Concise Oxford Dictionary_, the _Concise Dictionary of National Biography_, or the _Oxford Survey of the British Empire_ is obvious; and many people like to read the Poets and the Classics in thin and light volumes. The _Oxford Homer_ will go into a pocket, though it has 1,374 pages; and the India paper _Shakespeare_ and _Oxford Book of English Verse_ are delightfully easy to carry and handle. The Controller of the Mill is Mr. Douglas Clapperton (a name well known in the paper trade), who succeeded Mr. Joseph Castle in 1916. § 4. _The Press in London_ The association of the Oxford Press with London booksellers—the publishers of former days—goes back to early times. Apart from the negative agreement with the Stationers’ Company, _not_ to print Bibles and Almanacks, we find, at the end of the seventeenth century, Oxford Bibles bearing the imprint of various London booksellers. In 1776 Dr. Johnson wrote to the Master of University College a letter, printed by Boswell, in which he sets forth with knowledge and perspicacity the philosophy of bookselling; the moral of the discourse is that the University must offer more attractive discounts to the book trade—a doctrine which has been adopted in modern times, though in 1776 it perhaps fell upon deaf ears. Not later than 1770 a Bible Warehouse was established in Paternoster Row. But it was not until a century later that the Press undertook the distribution in London of its secular books. In 1884 these books, formerly sold by Messrs. Macmillan, were taken over by the Manager of the Bible Warehouse, Mr. Henry Frowde, who thus became sole publisher to the University; an office which he continued to hold with great skill, devotion, and success until on his retirement in 1913 he was succeeded by Mr. Humphrey Milford.
