This study reviews the current status of public library service in Metropolitan Dade County, Florida, with particular reference to: (1) the governing structure of the existing public library agencies; (2) the sources and levels of their financial support; (3) the available library facilities, resources and personnel; (4) the services that are provided; (5) the uses made of these libraries by their patrons; and (6) the patrons' attitudes toward these agencies. The study recommends a library facilities master plan that calls for the establishment of a county library system to be operated by Dade County with headquarters at the existing Miami Public Library. The master plan suggests a new headquarters facility in Miami, the building of four regional libraries in various parts of the county, the establishment of new branch facilities, the expansion of certain existing facilities and the closing of others. The study suggests that some of the libraries' existing services ought to be intensified and that various new services need to be provided. A timetable for the implementation of the governing structure for the county library system, the methods of providing financial support for its operation, and the procedures for financing the recommended construction program are included.
