As an integral part of the library improvement program of the Atlanta Public School System, the library aide program, funded under Title I of the Elementary and Secondary Education Act, was developed to relieve librarians of routine clerical and nonprofessional duties. In order to evaluate the inservice training and library aide activities, adaptations of the locally developed multi-purpose instrument, "Determining Task Assignments in Libraries" (D-E-T-A-I-L), were used to (1) evaluate a summer workshop for librarians, (2) determine the nature and extent to which library services were performed for classroom teachers and pupils, and (3) determine the nature and extent to which library aides performed nonprofessional library tasks. The Atlanta-Library Aide Observation Survey (A-LAOS) was used to ascertain the librarians' perception of the performance of library aides in the elementary schools, and a statistical report was made on the materials processed at the Central Processing Center. It was found that the library aide program has made it possible for librarians to assume more professional duties, that the planning and development of the Central Book Processing Center has been a significant success, and that the team work situations have been a major source of strength in the program. Specific recommendations are made for expanding and improving the program. Appendixes include a bibliography of 28 items and data from the D-E-T-A-I-L subtests. (Author/JB)
