The Reader Development Program (RDP) of the Free Library of Philadelphia was begun in 1966 with funds from Title I of the Library Services and Construction Act. The program was created in order to develop a demonstration reading program to reach and help the culturally disadvantaged. The RDP involves three approaches in providing library service to the deprived. (1) It attempts to make available materials which will meet the vocational, cultural, and recreational needs of young adults and adults who have an 8th grade reading level or lower. (2) It attempts to encourage nonreaders with a higher reading level to read. (3) It attempts to instill in underprivileged children a love of reading through story hours, book talks, and easy availability of children's literature to children and their parents and teachers. The RDP also coordinates its services with those of other agencies and organizations working with the deprived. (CC)
