The needs for supplementary training of library personnel from increased demands on libraries for services, increased rates of personnel turnover, and a growing lag between personnel retraining practices and the rapidly changing requirements for personnel performance. The initial project covers (1) reference tools and procedures, (2) foreign and technical terminology, and (3) applications of modern technology in libraries. The training approach emphasizes flexibility and modularity in the course materials and trainee-directed self-testing and study. The work to be carried out in the project includes: (1) task performance requirements analysis, (2) training requirements analysis, (3) construction and pilot testing of the lesson packages, (4) construction of diagnostic tests for the skills and knowledges covered in the courses, (5) running of an evaluation experiment to test the overall effects of the training courses, and (6) documentation of these activities and materials. The products to be delivered from this project include: (1) training course packages, (2) documentation of the methods and procedures developed in analyzing the requirements for, and constructing, the training courses; and (3) a report of the evaluation study. Possibilities for application of the project approach to other areas of library personnel training requirements are discussed. (Author/JB)
