keeping up a continually augmenting catalogue in print was seriously considered, until, in October 1861, it was proved by the introduction of print into the University Library of Cambridge. Some years afterwards the system was strongly pressed upon the attention of the Museum by the Treasury, which had remarked the gradual and inevitable increase of expenditure in binding, breaking up, interleaving and relaying the volumes of the manuscript catalogue, increased by this time from 150 to 1500. I well remember the pains which Mr. Rye, then keeper of the printed books, took in investigating the subject, and I believe I may say that had it depended upon him, the transition to print would have been effected immediately. Other views, however, prevailed for the time; and when, in October 1875, the subject was again brought forward by the Treasury, it fell to my lot to treat it from a new point of view, suggested by my observations in my capacity as superintendent of the Reading Room. I saw that, waiving the question as to the advantage or disadvantage of print in the abstract, it would soon be necessary to resort to it for the sake of economy of space. There were by this time 2000 volumes of manuscript catalogue in the Reading Room, exclusive of the catalogues of maps and music. There would be 3000 by the time that the incorporation of the general and supplementary catalogues was complete. Hundreds of these volumes in the earlier letters of the alphabet were already swollen with entries, and required to be broken up and divided into three. Sooner or later every volume would have undergone this process. By that time there would be 9000 volumes of manuscript catalogue, three times as many as the Reading Room could contain, or the public conveniently consult. The only remedy was to put a check upon the growth of the catalogue by printing all new entries for the future, and to mature meanwhile a plan for converting the entire catalogue into a printed one. I prepared, at the request of Mr. Bullen, a memorandum embodying these ideas, and entered into the subject more fully when, in January 1878, it was again brought forward by the Treasury. These views, however, did not find acceptance at the time. Mr. Winter Jones, and Mr. Newton, acting on the latter occasion as deputy Principal Librarian, were, indeed, both theoretically in favour of print; but it was thought that the desired financial economy, the only point on which the Treasury laid any stress, could be better obtained by the employment of Civil Service writers. The question was thus left for Mr. Bond, who became Principal Librarian in the following August. As keeper of the manuscripts, Mr. Bond's attention had never been officially drawn to the catalogue of printed books, but, as a man of letters, he had formed an opinion respecting it; and I am able to state that he came to the Principal Librarianship as determined to bestow the boon of print upon the catalogue and the public, as to effect the other great reforms that have signalised his administration. From the moment of his accession the question may be said to have been virtually decided. In April 1879, I published an article in the New Quarterly Magazine, foreshadowing almost everything that has since been accomplished. In the summer of the same year, Mr. Bond, having secured the concurrence of the Trustees, proposed to the Treasury to substitute print for transcription in the case of all additions henceforth made to the catalogue, a proposal which the Treasury could not refuse to entertain, as it had originally come from itself. It was accordingly accepted; the details of the scheme were settled by Mr. Bond in concert with Mr. Bullen and the assistant keepers; the general supervision of the printing was entrusted to my colleague Professor Douglas; and by the beginning of the new year the press was fully at work. We had thus successfully introduced print into the catalogue, and by diminishing the size of the entries checked the enormous pressure upon our space which threatened to swamp the catalogue altogether. We had also, by providing for the issue of the new printed titles in parts at regular intervals, enabled any subscriber to obtain a complete list of future additions to the Museum. But this related to the future only; nothing had yet been done to meet the public demand for a printed catalogue of all books already in the Library. The satisfaction of this demand was the second item in Mr. Bond's programme. In recommending his proposal to the Treasury, he relied upon the same grounds that had been shown to exist in the case of the Accession Catalogue. He pointed out the enormous number of manuscript volumes, the ponderous unwieldiness of many among them, the expense of perpetual breaking up, rebinding, and relaying; the manifest advantage of compressing many volumes into one, and providing space for additions for a practically indefinite period. On these grounds, and not on literary grounds, the Treasury assented to the proposal, and agreed to devote, for as long as they should see fit, a certain annual sum for the gradual conversion of the manuscript into a printed catalogue. It is desirable that this should be thoroughly understood, as it affords the answer to some questions which may very naturally be asked respecting the method of publication adopted for the catalogue. Why is it not brought out at once, complete from A to Z? Because the Treasury have not granted £100,000 for the purpose. They simply make an annual allowance of limited amount, liable to be withdrawn at any time. Might not, however, the allotted sum be employed as far as it will go in printing the catalogue consecutively from the beginning, instead of in selected portions? To this there are several things to be said. The grant is made upon condition that it shall before all things be employed in remedying the defects signalised by ourselves, bringing cumbrous, overgrown volumes into a handy form, and putting a stop to the perpetual rebinding and relaying. The most bulky volumes, therefore, must in general be those selected for printing. An equally powerful consideration is that we thus escape all danger of the reproach that has hitherto attached to almost every similar undertaking, "This man began, and was not able to finish." The funds on which we relied might at any time fail us, and we might never progress beyond our A, B, C. By making the printing a portion of the daily life of the institution, a piece of administrative routine like cataloguing or binding, we escape alike ambitious professions and ambitious failures. Once more, a strictly alphabetical procedure would destroy one of the most valuable features of the scheme, the separate issue of important special articles, not merely to our limited body of subscribers, but offered on a large scale to the public generally. We have already the article Virgil in the press on this principle, and it is hoped that Bible, Shakespeare, Milton, Homer, Dante, Academies, Periodicals, and others, may ere long be added to the list. Even our ordinary volumes frequently contain articles better printed now than twenty years hence: one of the last completed, for instance, contains the article Gladstone. It would indeed be well if our resources admitted of these three operations being carried on simultaneously, the consecutive publication of the catalogue, the compression of overgrown volumes wherever occurring, the independent issue of important special articles. With sufficient means to defray the additional cost of printing and provide the needful literary revision, all three might very well go on pari passu. I hope that the liberality of the Treasury, of which I desire to speak with every acknowledgment, will rise still nearer to the height of the occasion, and I believe it will. It will be seen that, granting the principle of the conversion of the manuscript catalogue into a printed one, there is no economy, but the reverse, in spreading the operation over a long period. The longer it lasts, the greater will be the accumulation of titles for accessions, to be included in the general catalogue when the volumes to which they belong come to be printed in their turn. Supposing that the whole catalogue could be put into type to-morrow by the stroke of an enchanter's wand, we should have printed three millions of titles. If the metamorphosis were deferred for forty years, we should then print five millions. But if the work of printing goes on during the forty years, as at its present rate of progress it will, we shall have printed and paid for six millions, because half of the two million accession titles will have been printed and paid for twice over, first as accession titles, and again after their incorporation into the general. It is not, however, so much upon such economical considerations that I rely, as upon the conviction that the Government will ultimately recognise our work as a truly national one; to which end the people itself must contribute by a wider and warmer recognition and a more liberal pecuniary support than has as yet been accorded. Before entering further into this department of the subject, I will briefly state what has been effected already, and describe the method of procedure. Of the Accession Catalogue I have already spoken at Manchester, and I have little to add to my observations upon that occasion. The titles written for new acquisitions, instead of being transcribed fourfold, are now sent to the printer as soon as a sufficient number have accumulated. They are divided into three principal sections; new English and foreign books; old English books; old foreign books. They come back printed in regular alphabetical order, and after the press has been corrected are distributed to subscribers and such institutions as receive them gratuitously. Four copies are cut up, and the titles inserted into the General Catalogue in their proper places, occupying a mere fraction
