This master plan for library development in the Commonwealth of Pennsylvania reviews the accomplishments of the five year plan for 1976-81, examines the current status and services of libraries, and establishes goals and objectives for the 1982-87 period. A review of the status and accomplishments of the original eight goals and 30 objectives is followed by an overview of the current status of Pennsylvania libraries, their needs, and those of some residents specifically identified in LSCA as recipients of special services. The final section outlines four primary goals and 20 subsidiary objectives, believed to be realistic and achievable through the use of federal funds, that will increase existing library resources and improve library services provided by all types of commonwealth libraries.
