One valuable security against fire may probably be found to be the cases invented by the eminent bookbinder Mr. Zaehnsdorf, for the protection of books of especial value. They have successfully borne the ordeal of an actual conflagration at the burning of Lord Carysfort's library, and have been tested with encouraging results by the present Keeper of Printed Books at the British Museum. On this occasion the only part of the paper charred was that actually in contact with the inside of the case, which would not have happened at all if the books tested had been bound. The expense of such cases is, nevertheless, a serious obstacle to their employment, but in practice it would probably be found that separate cases were unnecessary, and that it might even suffice to line the shelves with the incombustible material.
The flooring of the public rooms of libraries should be as noiseless as possible, and of a material that is warm to the feet, and capable of being readily cleaned. The entrance halls and lobbies will be best paved with mosaic or encaustic or glazed tiles. These should be of a light colour, for this part of the building is generally the worst lighted. Stone floors laid in large squares are not recommended, as they are apt to wear irregularly. Marble looks well, but has been condemned by many for its sonorousness.
In the reading-rooms and reference library wood is generally used. If it is not intended to cover the floors, the best floor will be one made of wooden blocks laid upon a cement foundation.
