Childrens Department, on first floor, south wing. Here are located the offices of the department, three children's reading rooms, the children’s study room and the teachers’ reading room. The work of the department is not confined to the children’s rooms at the Central Library and branches. It has a collection of 31,000 books for children’s reading which are circulated only through the city schools. It also places small collections of books, called home libraries, in many parts of the tenement district, where little reading clubs are conducted among a class of children who would not otherwise enjoy the use of the Library.
The Carnegie Library School, which is under the management of the Library, is also in this wing. Its object is to train young women for library work with children. More than 250 of its former students are now serving as children’s librarians in various parts of the country.
