The prefatory section of the Library of Congress (LC) annual report lists library officers, library committees, consultants, and an organizational chart. The body of the report begins with a narrative overview of recent LC activities in such areas as organizational changes, copyright law, Bicentennial Program, publications, and projects. Separate chapters are devoted to the activities and achievements of LC's seven major components: Processing Department, Congressional Research Services, Reader Services Department, Research Department, Law Library, Administrative Department, and Copyright Office. Appendices include an annual report of LC's Trust Fund Board; statistics and financial data on acquisitions, cataloging, photoduplication, reader services, employment, and special services; and lists of exhibits, concerts, lectures, legislation, special programs, and publications sponsored by LC. Since a change in the fiscal year occurred, a special appendix is devoted to the transitional quarter from July 1, 1976 to September 30, 1976. An index is included. (JPF)
