Library development has followed much the same course as the development of the school. Beginning with institutions of higher learning for the rich and leisure class, the school came gradually to concern itself with the education of the children of the masses, rich and poor alike. Following the development of colleges and universities, the secondary and elementary urban schools were pretty well equipped to give the city child the best possible training, but the rural schools still suffered from lack of funds and proper equipment. Now the efforts of educators are bent toward giving the child in the country educational opportunities equal to those of the city child. In much the same way the library of the Middle Ages served only the rich and scholarly. Fifty years ago libraries began to provide books for the people who lived in cities or within easy reach of them. The rural districts, however, were entirely without the benefit of libraries. Today one of the most active developments of the library is to be seen in the effort to bring to the people in remote districts book facilities, equal to those which have long been available to residents of cities and towns. The following two topics are discussed in this bulletin: (1) Library service (Sabra W. Vought); and (2) A decade of school-library achievement (Edith A. Lathrop). (Contains 49 footnotes.)
