This study outlines the types of library service required to furnish quality reference services to state agencies. The services provided by the Oregon State Library were evaluated according to the standards established by the American Library Association. Evaluation of the collection for scope and coverage in subject areas of automation, behavioral sciences, civil engineering, departmental libraries, economic planning, indexes and abstract services, information storage and retrieval, institutions, nursing, personnel, public finance and state government showed that the collection meets the needs of government and that the basic tools for providing quality service are available. Weaknesses exist in special reports and studies by private associations and organizations. Suggestions for making the available resources known to users are given along with suggested acquisitions in behavioral sciences, blind, medical library and reference, mental retardation, nursing, periodicals and rehabilitation literature. A list of bibliographies consulted for evaluation purposes is appended. (AB)
