Proceeding now to the subject of library buildings, reading-rooms, and furnishings, it must be remarked at the outset that very few rules can be laid down which are of universal application. The architectural plans, exterior and interior, of such great institutions as the Library of Congress, or the Boston Public Library, with their costly marbles, splendid mural decorations, and electric book-serving machinery, afford no model for the library building in the country village. Where the government of a nation or a wealthy city has millions to devote for providing a magnificent book-palace for its library, the smaller cities or towns have only a few thousands. So much the more important is it, that a thoroughly well-considered plan for building should be marked out before beginning to build, that no dollars should be wasted, or costly alterations required, in order to fit the interior for all the uses of a library. The need of this caution will be abundantly evident, in the light of the unfit and inconvenient constructions seen in so many public libraries, all over the country. So general has been the want of carefully planned and well-executed structures for books, that it may fairly be said that mistakes have been the rule, and fit adaptation the exception. For twenty years past, at every meeting of the American Library Association, the reports upon library buildings have deplored the waste of money in well-meant edifices designed to accommodate the library service, but successful only in obstructing it. Even in so recent a construction as the Boston Public Library building, so many defects and inconveniences were found after it was supposed to have been finished, that rooms had to be torn out and re-constructed on three floors, while the pneumatic tube system had been found so noisy as to be a public nuisance, and had to be replaced by a later improved construction.
