It seems a notable fact that courses of lectures, which have had a prominent part in the work of the Children's Museum, were also an important factor in the earlier educational work connected with the library; and also that a "Library fund," established sixty or more years ago, still provides all books and periodicals for the Children's Museum Library, with the addition of a small annual gift from the state of New York, the cost of maintenance being assumed by the city of New York. The establishment of the Children's Museum came about in this wise. After a serious fire in the Washington street building, and the subsequent sale of its site, the Brooklyn Institute of Arts and Sciences secured an indefinite lease of a fine old mansion located in Bedford Park, which had been recently acquired by the city. The collections of birds, minerals, and other natural history objects were placed on exhibition for a few years in this old mansion, and the library, which now numbered several thousand volumes, was stored in the same building. On the completion of the first section of the new Museum of the Brooklyn Institute of Arts and Sciences, in 1897, the major part of the natural history collections were installed in the new museum. At length the idea occurred to one of the curators that the old building could be utilized to advantage by establishing a museum which should be especially devoted to the education and enjoyment of young people. The first beginnings were made by the purchase of natural history charts, botanical and zoological models, and several series of vivid German lithographs, representing historical events ranging from the Battle of Marathon to the Franco-German War. Some collections of shells, minerals, birds and insects were added, and the small inception. of the Children's Museum was opened to the public Dec. 16, 1899, in a few rooms which had been fitted up for the purpose. A large part of the Brooklyn Institute Library, which had been stored in the building, and which was no longer useful here, was sent to other libraries in the South, leaving such books as were suitable to form the nucleus of the Children's Museum Library as well as the Library of the Central Museum.
