One of the chief charms of the books of the fifteenth century is that they are so unlike those of our own day. In the first year of its successor a great step was taken towards their modernization by the production of the first of the Aldine octavos, and the process went on very rapidly. In the early days of printing all the standard works of the previous three centuries that could by any possibility be considered alive were put on the press. By 1500 men were thinking of new things. New editions of many of the old religious and didactic treatises, the old poems and romances, continued to be printed, though mostly in a form which suggests that they were now intended for a lower class of readers, but the new publishers would have little to do with them. Scholarship, which till now had been almost confined to Italy, spread rapidly to all the chief countries of Europe, and amid the devastation which constant war soon brought upon Italy, was lucky in being able to find new homes. With the new literary ideals came new forms for books, and new methods of housing them. Before 1500 several publishers had found it worth their while to print editions in five huge volumes of the _Speculum_ of Vincent de Beauvais, each volume measuring eighteen inches by thirteen and weighing perhaps a dozen pounds, though paper in those days was not yet made of clay. These great volumes had been cased in thick wooden boards, covered with stout leather and protected with bosses or centre-pieces and corner-pieces of metal. They were not intended to stand on shelves like modern books, but were laid on their sides, singly, on shelves and desks, and from pictures which have come down to us we can see that the library furniture of the day included a variety of reading-stands with the most wonderful of screws. The men for whom Aldus catered wanted books which they could put in their pockets and their saddlebags, and it was not long before the publishers of Paris and Lyon outdid Aldus in the smallness and neatness of their editions. Of course large books continued to be issued. The _Complutensian Polyglott_ will not easily be got either into a pocket or a saddlebag, but it is a good deal smaller than the _Speculum_ of Vincent de Beauvais, and, speaking generally, small folios took the place of large folios, and octavos the place of quartos, and in a little time the octavos themselves were threatened by the still smaller sextodecimos. There is, indeed, no stop till in the seventeenth century we come to the tiny Elzevirs, which remained the last word in book-production until the diamond editions of Didot and Pickering.
