The object of the room is not only to perform the usual work of a children's room, but also to interest and help parents and others in selecting children's reading. Authors, artists, and publishers come here for information about books for children. Another purpose is to furnish suggestions for similar rooms elsewhere. A number of libraries, in other parts of the world, have adopted suggestions which they found here. Exhibitions on various subjects are held from time to time, and there is a collection of children's books of the old-fashioned kind. Open 9 a. m. to 6 p. m. week days. [Illustration: CHILDREN'S ROOM] =Library School.= Here a two years' course in training for library work is given to a body of students averaging about seventy-five in number. The office of the School (where inquiries should be made) is in Room 75, on the inner or western side of the corridor which runs along the front of the building, parallel to Fifth Avenue. The Library School class room, not open to the public, is on the other side of the corridor. =Public Telephones.= The public telephones are in Room 70, on the inner or western side of the front corridor. =Business Offices.= The rest of the basement floor is occupied by offices, open only to those who have business engagements therein. The offices include that for Printing and Binding (No. 58), and the Shipping Room (No. 51). In the Printing Office the catalogue cards of the Library, printed forms, and all the Library's publications are printed. For the publications, see page 78. =Travelling Libraries Office.= The entrance to the Travelling Libraries office is from Bryant Park, at the southwest corner of the building. The office itself is not of interest to sightseers. As it is under control of the Circulation Department, its work is described on page 59.
