The chief faults of bookcases arise from their being designed and made by men who have never used a book. A first requisite in bookcases is simplicity, bearing in mind that the books are the ornament and not the bookcases. The cabinet-maker, among other things, is too fond of embellishments, and sacrifices space to what seem odd angularities and irregularities.

No bookcase should be above eight and a half feet in height. No ladder should be necessary to get at books. If books are 'skied' up to the ceiling they must suffer from the heated air. It is heat, not gas merely, which damages books.

A room may be made to look very beautiful by being surrounded with fumed oak bookcases, eight feet high. The shelves should be made movable with Tonks' patent.[42] Mr. Gladstone[43] speaks of the looseness and the tightness of movable shelves, the weary arms, the aching fingers, and the broken finger-nails. This can be avoided by the use of the patent here named. The bottom cases should be deeper and wider, to take quartos and folios, but there should always be an extra shelf for turning a folio section into an octavo section. Nineteen-twentieths of the books in circulation are octavos and smaller volumes. On each side of the fireplace there should be an arm projecting about four feet and a half. The inner side of this should have a comfortable reading-seat, and on the outer side, farthest from the fire, there may be shelves for books. If the structural arrangements of the room admit of these projecting arms being placed, without sacrifice of comfort, at a greater distance from the fireplace, the books may be placed on the upper part of the inner side as well, the lower part being used as a lounge.

It must be remembered that heat and excessive dryness are fatal to good bindings and, indeed, to all parts of a book, and therefore no bookcase should approach too near a fireplace, nor should bookcases be placed backing upon hot-water pipes. The shelves should be edged with leather and such leather must not be stiffened by cardboard or brown paper—simply leather, and there should be a roller shutter of silk to draw down in front of the books during absence from home. The cases[44] should everywhere be perfectly flush, without any sort of protruding ornament. It will be found a great advantage to make the framework of the various cases of equal dimensions, so that the shelves can be made transferable. In estimating the extent of shelving which it may be necessary to provide, we may calculate that in an ordinary library a space two feet high and two feet wide will, on an average, contain about thirty-five volumes, and it may be estimated roughly that every thousand volumes in a library will require about a hundred square feet of shelving.

If fixed shelves are made, the usual height will be—[45]

These spaces will allow ample room for the average sizes. The 'Atlas' folios and 'Elephant' folios are best accommodated in single shelves, in which they may be flat, or on trays or table cases.[46] Bear in mind always to allow sufficient space for expansion. Nothing causes more disorder than insufficient shelf accommodation. All cases should be numbered and lettered, that is, each section should have a number, and each shelf a letter. For the accommodation of expensive bindings or rare books and MSS., a special case may sometimes be required. Very beautiful specimens of such may be seen sketched in the books of Chippendale, Sheraton, and Heppelwhite, but it is in all cases better to avoid glass fronts and adopt ornamental brass wire work if any special protection be needed.

The late Mr. Blades, a great expert in this matter, said, 'It is a mistake to imagine that keeping the best-bound volumes in a glass-doored bookcase is a preservative. The damp air will certainly penetrate, and as the absence of ventilation will assist formation of mould, the books will be worse off than if they had been placed in open shelves. If securing be desirable, by all means abolish the glass and place ornamental brass wire work in its stead.'[47]

'It is more important to see that the shelves intended for choice and richly bound books should be covered with leather, and expressly such as are intended for books of large sizes. In the case of books of special value, the leather should be well padded, should be of the best quality, and should have a polished surface.'[48]

In the Nineteenth Century for March, 1890, already quoted from, Mr. Gladstone wrote upon 'Books, and the Housing of them.' This paper showed a sound grasp of the subject and showed Mr. Gladstone in a new and very interesting light. Appended are some extracts from this paper, all of which I think experts would agree to, except the fixed shelves, and here, I think, any one who has handled books very much will be at issue with Mr. Gladstone. He himself says:—'I have recommended that, as a rule, the shelves be fixed, and have given reasons for the adoption of such a rule. I do not know whether it will receive the sanction of authorities, and I make two admissions. First, it requires that each person owning and arranging a library should have a pretty accurate general knowledge of the size of his books. Secondly, it may be expedient to introduce here and there, by way of exception, a single movable shelf.'

Now, a man must be able not only to gauge very accurately the limits of his library and the various sizes of books, but he must be able to look into the future if he would safely embark on fixed shelves. And this is wholly impossible. Fixed shelves should only be adopted where cost has to be reduced to a minimum, but in the majority of instances movable shelves will be found preferable. The paragraphs which deal with bookcases in Mr. Gladstone's article may here be given:—

'The question of economy, for those who from necessity or choice consider it at all, is a very serious one. It has been a fashion to make bookcases ornamental. Now, books want for and in themselves no ornament at all... The man who looks for society in his books will readily perceive that, in proportion as the face of his bookcase is occupied by ornament, he loses that society; and conversely, the more that face approximates to a sheet of book-backs, the more of that society he will enjoy. And so it is that three great advantages come hand in hand, and, as will be seen, reach their maximum together: the sociability of books, minimum cost in providing for them, and ease of access to them.

'In order to attain these advantages, two conditions are fundamental. First, the shelves must, as a rule, be fixed; secondly, the cases, or a large part of them, should have their side against a wall, and thus, projecting into the room for a convenient distance, they should be of twice the depth needed for a single line of books, and should hold two lines, one facing each way. Twelve inches is a fair and liberal depth for two rows of octavos. The books are thus thrown into stalls, but stalls after the manner of a stable.... This method of dividing the longitudinal space by projections at right angles to it, if not very frequently used, has long been known. A great example of it is to be found at Trinity College, Cambridge, and is the work of Sir Christopher Wren. He has kept these cases down to a very moderate height; for he doubtless took into account that great heights require long ladders, and that the fetching and use of these greatly add to the time consumed in getting or replacing a book.'

It must here be added that Mr. Gladstone's plan is much more fitted for a large public library than for the library of a private person, for whom he is prescribing. Though the library in the form of an annexe[49] is in many ways an ideal form for housing a large library, yet these are hardly likely to be in the majority, and most people find that they have to house their books in a circumscribed space, with no room for such bays and projections as he suggests except perhaps one by the fireplace.
