This report presents the results of a major 5-year review by the State Library of Pennsylvania Advisory Council on Library Development of the 1984 Comprehensive Plan for Library Service in Pennsylvania, together with related resolutions adopted by delegates to the 1990 Governor's Conference on Library and Information Services. The council review covered the seven issues, two goals, and five objectives identified by the comprehensive plan and discussed additional issues which might have emerged during the past 6 years, or issues that are no longer relevant. They also reviewed 19 recommendations from the 1984 comprehensive plan, which fall into three broad areas: quality of library service, materials and resources, and management practices. It is noted that both the conference and the comprehensive plan called for the improvement of library service in all types of libraries, with specific recommendations for public library service. The report includes: (1) a compilation of the process used in the council's review; (2) subcommittee reports, council discussion and conclusions, and the 1989 conference resolutions that pertain to each recommendation; and (3) a summary of activities that still need to be addressed.
