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.

Miscellaneous Appliances.

Whether the library be considered as a workshop or a morning-room, there are certain necessary appliances, which will contribute a great deal to comfort, and the proper preservation of books. Thus, proper tables will be required. Mr. Gladstone, I believe, has, or had, three tables in his Temple of Peace—one for correspondence, one for politics, and one for literary work. This, no doubt, is a very excellent plan to be followed by those whose time is precious, and who have to divide each day up for fixed duties. The 'Shannon' and other American tables are very excellent for correspondence work, being fitted with pigeon-holes and drawers, and I have no doubt but that equally well-made tables are made specially fitted for literary work. Such a table should measure not less than six feet by three; its top should be a clear, flat surface, and it should stand firmly on its legs, and these legs should be four, and should not be placed to be in the way of the person sitting at the table. An ink-well should be sunk flush with the top of the case, and it should have a brass cover. A knee-hole table is not the best for literary work, but it may be the best for letter-writing. Of chairs, one good, firm, hard-seated chair is necessary. Mr. Ellwanger[50] says, 'I have two chairs for my reading—a stiff one for books I have to read; a luxurious one for books I like to read. My luxurious chair is of dark green leather, a treat to sink into, modelled after the easy armchair of the Eversley Rectory, known from its seductive properties as "Sleepy Hollow."' A very prettily designed and useful hard-seated chair is that known as the Goldsmith chair, being modelled upon the chair which belonged to Oliver Goldsmith. A revolving bookcase is a very appropriate article of furniture in a library. It may be made especially useful for reference-books, or any such books as are being used together at one time for purposes of study and comparison. These revolving bookcases are made in all sizes, and can, of course, be made to suit any particular requirement; thus I have seen them made with a top which can be raised to a slope with a ledge like a standing desk, upon which a large atlas can be rested and consulted. Apart from this, I strongly recommend the use of a standing desk for health's sake when a great deal of writing has to be done.
