This guide presents practical information about planning a school library media center budget in consideration of the goals and objectives of the district, the school, and of the particular programs involved, both for the year under consideration, and for the future. Three chapters are devoted to discussions of initiating a budget, the Iowa budget format, and other components of a school library budget. Four sample replacement cycles and costs charts for selected library media for elementary, junior high/middle schools, senior high schools, and area colleges are provided for basic, initial or phase one collections for cycles from 2 years to 33 and one-third years. Sample maintenance and development budgets for a junior-senior high school with an enrollment of 500, as well as several budget templates, are also presented. A listing of subaccount codes typically used in Iowa library media programs is appended. (MAB)
