where men have dwelt from the age of Hercules to the age of Heraclius. The Museum was founded by a great physician; the library, therefore, rests upon a sound substratum of old medical books. The King was the next important benefactor; next above early medicine and natural history, accordingly, comes a stratum of royal libraries from the first Tudor to the last Stuart, each a miniature representative of the best literature of its time. The Hanoverian sovereigns, though no great patrons of letters, were diligent collectors of pamphlets: hence the priceless collection of Civil War and other important tracts which immediately succeeded the donations already mentioned. As the growth of the Museum attracted further liberality ("To him that hath shall be given"), the collection naturally took an impress from the tastes of the private collectors by whom it was enriched. Hence abundant wealth in classics and the early literature of the Latin family of languages, accompanied by poverty in languages which the collectors did not understand, and subjects for which they did not care. When, thanks to Panizzi, the library at last obtained an adequate grant for purchases, the librarian's own intelligence became a much more important factor than formerly. To continue our metaphor, the contents of the recent strata would be found far more composite than of old, and more puzzling to the intellectual geologist. He would come upon various fragmentary formations, as it were, in which, trifling and remote effects of prodigious causes, he would discern vestiges of the
great events of the time. Thus the growth of Greater Britain is legible in piles of colonial newspapers, and the Paris Commune is represented by a mass of caricatures and the scorched books of an Imperial Prince, literally saved out of the fire. It is the librarian's business at once to profit by this tendency to the accumulation of specialities, and to counteract it: to take advantage of every opportunity that may arise of enriching the library in definite directions, and at the same time of providing for the steady influx of miscellaneous literature, alike of the past and of the present as regards foreign nations: of English contemporary literature the Copyright Act, as above explained, takes sufficient care. It seems paradoxical, but it is true, that the Museum should be the home both of the books which every one expects to find in it, and of those which no one expects to find—of the literary freight which can ride the ocean, and of that which would perish without the haven of a public library. The catalogue must be the mirror of the library, and it is not the least of the many advantages of print that the public have now much better means than formerly of judging how the most difficult functions of librarianship have been understood and discharged at the Museum. In this connection mention may be made of a minor feature of the publication of the catalogue of considerable importance: the issue of extra copies of special articles as excerpts, sold separately at the lowest possible price. In this manner bibliographies, complete as far as the Museum collections are concerned, of Aristotle,
Bacon, Bunyan, Byron, Dante, Goethe, and other writers of special importance have been issued. These should be of great value to students, and would probably have a large sale if their existence were more generally known. At present, like other Museum publications, they suffer from imperfect publicity. Another very valuable appendix to the catalogue of printed books is the catalogue of maps and plans, reduced, under Professor Douglas's direction, from upwards of three hundred of MS. to two volumes of print as issued to the public, or fourteen as laid down for use in the Reading Room. The four hundred and fifty MS. volumes of the catalogue of music, it is hoped, are on the eve of undergoing similar treatment.
Apart from the errors which must inevitably creep into so vast a work, dealing with such a variety of languages and literatures, and now in progress for more than fifty years, a considerable amount of imperfection is evidently inseparable from the very nature of the undertaking. It does not and cannot represent the condition of the library at any given moment. The volumes containing A, for example, will comprise the books under that letter possessed by the Museum in 1882 or 1883; but T, which for reasons which we have no space to explain, will probably be the last letter to be printed, will represent the condition of the library, as regards that letter, about the year 1900. During the whole progress of the catalogue an incessant shower of new titles representing the new books continually being
acquired, will have been descending at the rate of some 40,000 a year. Those belonging to letters not yet at press will have been taken up and absorbed by the catalogue in its progress; those belonging to the letters already in type must fall into a supplement. The article Thackeray, therefore, will be more complete than Dickens, and Thucydides than Herodotus. As concerns the student at the Museum, this is of no importance; the additions being regularly incorporated in the Reading Room catalogue in the manner above described. The catalogue as issued to subscribers, however, is necessarily imperfect and irregular. Supposing, for example, that Lord Tennyson and Mr. Browning were to simultaneously publish translations of Homer when the printing of the catalogue had reached the article Jones, Lord Tennyson's version would appear under Tennyson, but not under Homer, and Mr. Browning's version would not appear at all. There is but one way of obtaining a perfect index to the condition of the national library at a given time: the catalogue must be reprinted along with the numerous accessions which have been accumulating while the first edition has been going through the press—a national undertaking which will commend itself to men of letters more readily than to ministers of finance. Should, however, the completion of the catalogue nearly coincide with the commencement of the twentieth century, it may be hoped that this will be one of the many ways in which, if the new century does not, like its predecessors, find the
nation traversing a crisis, the epoch will assuredly be commemorated. It would remain to provide for the regular reprinting of the catalogue with its accessions at intervals, say of a quarter of a century. England would then possess a complete index to the growth of the national library, and the world would have the nearest approach to a register of all literature that, in the absence of any feasible scheme for a universal catalogue by co-operation among public libraries, it seems likely to obtain. Even this more ambitious project might be promoted if public libraries would consent to take the Museum Catalogue as a basis, and publish lists of such of their own books as are not to be found in it. By this means the expense and labour of cataloguing would be very greatly reduced, and the combination of these lists with the Museum Catalogue, when this came to be printed for the third time, say about 1925, would at last provide the desideratum of a universal register of literature.
Ambitious undertakings like these, however, depend upon the co-operation of many governments and many institutions. We can speak with more confidence of the efforts of the Museum to provide what is only second in importance to the catalogue itself—a classified index of its contents. With this object in view several copies of the catalogue are printed on one side only, that when completed they may be cut up, and the titles sorted according to subject, and re-arranged in classified lists. Thus by simply putting together all titles bearing the
press mark E, we shall obtain a separate catalogue of the Civil War Tracts; and a similar proceeding as respects the titles marked F, will afford a similar catalogue of the Croker collection of pamphlets on the French Revolution. Classed indexes to the literature of any subject can be made with equal facility, and as several copies of the catalogue will be available for treatment in the manner suggested, they may be varied for different objects, or to suit different systems of classification. For all strictly Museum purposes it would suffice to paste the titles excerpted on sheets of paper, but any of the indexes thus prepared might be printed and published. The only difficulty or delay would arise from the incorporation of the supplementary titles, which, as already explained, will have been continually added during the printing of the catalogue, and even this could be obviated by reprinting the entire catalogue as suggested above.
These hints, imperfect as they are, should convince the reader that the future of the Museum Catalogue, supposing the institution to be maintained in its present condition of efficiency, will not be less remarkable than its past. It will continue to make demands on the liberality of successive generations, which will be the more readily met the more the voluminous development of literature enforces the conviction that, next to positive addition to the world's stock of information, the most important service to culture is the preserving, arranging, and rendering accessible the stores which
the world already possesses. The recovery of the catalogue of the Alexandrian Library, if a less delightful, would probably be a more substantial gain to knowledge than the recovery of any individual author. But what the literature of the world is to the literature of ancient Greece, the Catalogue of the British Museum is to that of the Alexandrian Library.
