The number of such homogeneous series promoted by the Press during the last twenty years is large, even if all school-books are excluded. The _Oxford English Dictionary_ (which is of earlier origin) bulks so large in the public eye as somewhat to obscure all humbler enterprises; but it does not stand alone. In English literature the Press has built up in a quarter of a century a whole library of uniform series, all of respectable dimensions. The _Oxford English Texts_ are library editions of famous authors edited after exhaustive examination of the materials, in print and in manuscript, and handsomely printed from type; the _Tudor and Stuart Library_ consists of first editions and exact reprints of famous books of that period, printed in the types of the period on paper calculated to last for many centuries more; these books are now finding their way into the second-hand catalogues and the collections of connoisseurs; the _Oxford Library of Prose and Poetry_ is a series of little books for fanciers, offering especially the classics of the Romantic Revival in a form approximating to that of the originals; the _Oxford Poets_ claim to be the last word for accuracy of text, condensed yet fine printing, and the lowest price compatible with these qualities; the _Oxford Standard Authors_ offer the same texts as the Oxford Poets, together with many prose classics, in a cheaper form; the average volume containing nearly 600 pages of close yet legible print. Finally, the _World’s Classics_ furnish a collection of over two hundred of the most famous English books in a very handy form, still maintained in print as far as possible in spite of the costs of production, which make it increasingly difficult to keep any but the most popular books on sale in a cheap series.
