There is one class of libraries not yet touched upon, namely, school district libraries. These originated for the first time in a legally organized system, through an act of the New York State Legislature in 1835, authorizing the voters in each school district to levy a tax of twenty dollars with which to start a library, and ten dollars a year for adding to the same. These were not to be for the schools alone, but for all the people living in the district where the school was located. This was supplemented in 1838 by a State appropriation of $55,000 a year, from New York's share of the surplus revenue fund distributed by Congress to the States in 1837, and the income of which was devoted by New York to enlarging the school district libraries. After spending nearly two millions of dollars on these libraries in forty years, the system was found to have been so far a failure that the volumes in the libraries had decreased from 1,600,000 to 700,000 volumes. This extraordinary and deplorable result was attributed to several distinct causes. 1st. No proper responsibility as to the use and return of books was enforced. 2d. The insignificance of the sum raised by taxation in each district prevented any considerable supply of books from being acquired. 3d. The funds were largely devoted to buying the same books in each school district, instead of being expended in building up a large and varied collection. Thus the system produced innumerable petty libraries of duplicates, enriching publishers and booksellers, while impoverishing the community. The school district library system, in short, while promising much in theory, in the way of public intelligence, broke down completely in practice. The people quickly lost interest in libraries which gave them so little variety in books, either of instruction or of recreation. Although widely introduced in other States besides New York, from 1837 to 1877, it proved an admitted failure in all. Much public money, raised by taxation of the people, was squandered upon sets of books, selected by State authority, and often of inferior interest and utility. Finally, it was recognized that school district libraries were an evanescent dream, and that town libraries must take their place. This instructive chapter in Library history shows an experience by which much was learned, though the lesson was a costly one. The Historical libraries of the country are numerous, and some of the larger ones are rich in printed Americana, and in historical manuscripts. The oldest is that of the Massachusetts Historical Society, founded in 1791, and among the most extensive are those of the New York Historical Society, American Antiquarian Society, the Historical Society of Pennsylvania, the New England Historic-genealogical Society, and the Wisconsin State Historical Society. There are no less than 230 historical societies in the U. S., some forty of which are State associations.
