Already the increase of books is passing into geometrical progression. And this is not a little remarkable when we bear in mind that in Great Britain, of which I speak, while there is a vast supply of cheap works, what are termed "new publications" issue from the press, for the most part, at prices fabulously high, so that the class of real purchasers has been extirpated, leaving behind as buyers only a few individuals who might almost be counted on the fingers, while the effective circulation depends upon middle-men through the engine of circulating libraries. These are not so much owners as distributers of books, and they mitigate the difficulty of dearness by subdividing the cost, and then selling such copies as are still in decent condition at a large reduction. It is this state of things, due, in my opinion, principally to the present form of the law of copyright, which perhaps may have helped to make way for the satirical (and sometimes untrue) remark that in times of distress or pressure men make their first economies on their charities, and their second on their books. The annual arrivals at the Bodleian Library are, I believe, some twenty thousand; at the British Museum, forty thousand, sheets of all kinds included. Supposing three-fourths of these to be volumes, of one size or another, and to require on the average an inch of shelf space, the result will be that in every two years nearly a mile of new shelving will be required to meet the wants of a single library. But, whatever may be the present rate of growth, it is small in comparison with what it is likely to become. The key of the question lies in the hands of the United Kingdom and the United States jointly. In this matter there rests upon these two Powers no small responsibility. They, with their vast range of inhabited territory, and their unity of tongue, are masters of the world, which will have to do as they do. When the Britains and America are fused into one book market; when it is recognized that letters, which as to their material and their aim are a high-soaring profession, as to their mere remuneration are a trade; when artificial fetters are relaxed, and printers, publishers, and authors obtain the reward which well-regulated commerce would afford them, then let floors beware lest they crack, and walls lest they bulge and burst, from the weight of books they will have to carry and to confine.
