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.

It is plain, for one thing, that under the new state of things specialism, in the future, must more and more abound. But specialism means subdivision of labor; and with subdivision labor ought to be more completely, more exactly, performed. Let us bow our heads to the inevitable; the day of encyclopaedic learning has gone by. It may perhaps be said that that sun set with Leibnitz. But as little learning is only dangerous when it forgets that it is little, so specialism is only dangerous when it forgets that it is special. When it encroaches on its betters, when it claims exceptional certainty or honor, it is impertinent, and should be rebuked; but it has its own honor in its own province, and is, in any case, to be preferred to pretentious and flaunting sciolism.

A vast, even a bewildering prospect is before us, for evil or for good; but for good, unless it be our own fault, far more than for evil. Books require no eulogy from me; none could be permitted me, when they already draw their testimonials from Cicero[4] and Macaulay.[5] But books are the voices of the dead. They are a main instrument of communion with the vast human procession of the other world. They are the allies of the thought of man. They are in a certain sense at enmity with the world. Their work is, at least, in the two higher compartments of our threefold life. In a room well filled with them, no one has felt or can feel solitary. Second to none, as friends to the individual, they are first and foremost among the compages, the bonds and rivets of the race, onward from that time when they were first written on the tablets of Babylonia and Assyria, the rocks of Asia minor, and the monuments of Egypt, down to the diamond editions of Mr. Pickering and Mr. Frowde.[6]

It is in truth difficult to assign dimensions for the libraries of the future. And it is also a little touching to look back upon those of the past. As the history of bodies cannot, in the long run, be separated from the history of souls, I make no apology for saying a few words on the libraries which once were, but which have passed away.

The time may be approaching when we shall be able to estimate the quantity of book knowledge stored in the repositories of those empires which we call prehistoric. For the present, no clear estimate even of the great Alexandrian Libraries has been brought within the circle of popular knowledge; but it seems pretty clear that the books they contained were reckoned, at least in the aggregate, by hundreds of thousands.[7] The form of the book, however, has gone through many variations; and we moderns have a great advantage in the shape which the exterior has now taken. It speaks to us symbolically by the title on its back, as the roll of parchment could hardly do. It is established that in Roman times the bad institution of slavery ministered to a system under which books were multiplied by simultaneous copying in a room where a single person read aloud in the hearing of many the volume to be reproduced, and that so produced they were relatively cheap. Had they not been so, they would hardly have been, as Horace represents them, among the habitual spoils of the grocer.[8] It is sad, and is suggestive of many inquiries, that this abundance was followed, at least in the West, by a famine of more than a thousand years. And it is hard, even after all allowances, to conceive that of all the many manuscripts of Homer which Italy must have possessed we do not know that a single parchment or papyrus was ever read by a single individual, even in a convent, or even by a giant such as Dante, or as Thomas Acquinas, the first of them unquestionably master of all the knowledge that was within the compass of his age. There were, however, libraries even in the West, formed by Charlemagne and by others after him. We are told that Alcuin, in writing to the great monarch, spoke with longing of the relative wealth of England in these precious estates. Mr. Edwards, whom I have already quoted, mentions Charles the Fifth of France, in 1365, as a collector of manuscripts. But some ten years back the Director of the Bibliotheque Nationale informed me that the French King John collected twelve hundred manuscripts, at that time an enormous library, out of which several scores were among the treasures in his care. Mary of Medicis appears to have amassed in the sixteenth century, probably with far less effort, 5,800 volumes.[9] Oxford had before that time received noble gifts for her University Library. And we have to recollect with shame and indignation that that institution was plundered and destroyed by the Commissioners of the boy King Edward the Sixth, acting in the name of the Reformation of Religion. Thus it happened that opportunity was left to a private individual, the munificent Sir Thomas Bodley, to attach an individual name to one of the famous libraries of the world. It is interesting to learn that municipal bodies have a share in the honor due to monasteries and sovereigns in the collection of books; for the Common Council of Aix purchased books for a public library in 1419.[10]

Louis the Fourteenth, of evil memory, has at least this one good deed to his credit, that he raised the Royal Library at Paris, founded two centuries before, to 70,000 volumes. In 1791 it had 150,000 volumes. It profited largely by the Revolution. The British Museum had only reached 115,000 when Panizzi became keeper in 1837. Nineteen years afterward he left it with 560,000, a number which must now have more than doubled. By his noble design for occupying the central quadrangle, a desert of gravel until his time, he provided additional room for 1,200,000 volumes. All this apparently enormous space for development is being eaten up with fearful rapidity; and such is the greed of the splendid library that it opens its jaws like Hades, and threatens shortly to expel the antiquities from the building, and appropriate the places they adorn.

But the proper office of hasty retrospect in a paper like this is only to enlarge by degrees, like the pupil of an eye, the reader's contemplation and estimate of the coming time, and to prepare him for some practical suggestions of a very humble kind. So I take up again the thread of my brief discourse. National libraries draw upon a purse which is bottomless. But all public libraries are not national. And the case even of private libraries is becoming, nay, has become, very serious for all who are possessed by the inexorable spirit of collection, but whose ardor is perplexed and qualified, or even baffled, by considerations springing from the balance-sheet.

The purchase of a book is commonly supposed to end, even for the most scrupulous customer, with the payment of the bookseller's bill. But this is a mere popular superstition. Such payment is not the last, but the first term in a series of goodly length. If we wish to give to the block a lease of life equal to that of the pages, the first condition is that it should be bound. So at least one would have said half a century ago. But, while books are in the most instances cheaper, binding, from causes which I do not understand, is dearer, at least in England, than it was in my early years, so that few can afford it.[11] We have, however, the tolerable and very useful expedient of cloth binding (now in some danger, I fear, of losing its modesty through flaring ornamentation) to console us. Well, then, bound or not, the book must of necessity be put into a bookcase. And the bookcase must be housed. And the house must be kept. And the library must be dusted, must be arranged, should be catalogued. What a vista of toil, yet not unhappy toil! Unless indeed things are to be as they now are in at least one princely mansion of this country, where books, in thousands upon thousands, are jumbled together with no more arrangement than a sack of coals; where not even the sisterhood of consecutive volumes has been respected; where undoubtedly an intending reader may at the mercy of Fortune take something from the shelves that is a book; but where no particular book can except by the purest accident, be found.

Such being the outlook, what are we to do with our books? Shall we be buried under them like Tarpeia under the Sabine shields? Shall we renounce them (many will, or will do worse, will keep to the most worthless part of them) in our resentment against their more and more exacting demands? Shall we sell and scatter them? as it is painful to see how often the books of eminent men are ruthlessly, or at least unhappily, dispersed on their decease. Without answering in detail, I shall assume that the book-buyer is a book-lover, that his love is a tenacious, not a transitory love, and that for him the question is how best to keep his books.

I pass over those conditions which are the most obvious, that the building should be sound and dry, the apartment airy, and with abundant light. And I dispose with a passing anathema of all such as would endeavour to solve their problem, or at any rate compromise their difficulties, by setting one row of books in front of another. I also freely admit that what we have before us is not a choice between difficulty and no difficulty, but a choice among difficulties.
