The Learning Resources Center (LRC) represents a merger of library and audiovisual resources. The material in this publication consists of an overview of the various aspects involved in this merger. There are chapters on the emergence of the LRC: the library as LRC; LRC administration; resource centers in elementary schools, secondary schools, and colleges and universities; technical processes; individualized study; regional resource centers; special materials and facilities; the systems approach and behavioral objectives; and instructional development. There are bibliographies at the end of each section, and at the end of the document a glossary, a list of associations related to learning resources, and a list of addresses of some basic information sources.
