This program expresses a library philosophy that rests on the following principles: (1) That government--city, county, state, and federal--is responsible for the educational, economic, and cultural development of the society it serves; (2) That libraries are vital agents in the educational, economic, and cultural development of cities, counties, states, and nations, and, therefore, that library development is a responsibility shared by all levels of government; and (3) That since every citizen and every community should have equal opportunity to develop educationally, economically, and culturally, they should have equal access to the information materials they need to achieve that development. Most of the structures essential to make library service available to all Texans exist. Since improved service depends on building all components, much of the attention of this document is devoted to a discussion of these components, to ongoing programs to mesh services offered by them, and to proposals that will improve service. This presentation is organized to show how the plan was developed; the physiographic, demographic, and political environment in which libraries function; the present development of libraries; the needs and approaches to satisfying these needs; and methods for evaluating the success of programs undertaken.
