The project's second year (1967/68) was devoted to upgrading the computer operating software and programs to increase versatility and reliability. General conclusions about the program after 24 months of operation are that the project's objectives are sound and that effective utilization of computer-aided bibliographic data processing is essential to the objectives. The difficulty in debugging an integrated on-line system of programs, problems with transitions from non-automated to automated systems, and the lack of some necessary peripheral equipment for library operations have resulted in some delays. In 1967/68 the project involved the following tasks: A) development of bibliographic data processing system, B) implementation in library operations, C) character sets D) Project MARC, E) circulation, F) processing operations studies, and G) cooperative library systems development.
