Compiled by the Maricopa County Library Council, Inc., a countywide library planning body made up of representatives of the various sizes and types of libraries in Maricopa County, Arizona, this planning document describes the current level of development in the county's public libraries and presents recommended development goals for college, university, special, elementary, and secondary school libraries in the county. A number of difficulties associated with coordinated, cooperative planning efforts in a large, fast-growing area such as Maricopa County are discussed, and use of OCLC for collection development and interlibrary lending and borrowing is recommended to facilitate cooperation among libraries. In addition to statements of goals and objectives, this report includes an executive summary; background information on the community and its libraries; five charts/maps showing the geography of the county and various factors related to libraries; profiles of individual libraries of each type represented in the county; and a report on an assessment of the current status of library services and resources in the county, including levels of public library service, growth, governmental changes, interlibrary cooperation, and library education.
