Designed to aid elementary, middle, junior high, and high school library media staff in developing a quality collection, "Analysis of Client Groups" poses questions about students, faculty and administration, and parents and community. Brief discussions also consider methods for collecting data; review of student records; conversations with students and staff; review of school reports, newsletters, and community bulletins; and conducting surveys. "Black Studies: A Bibliography" provides full bibliographic information for 12 useful selection tools and 12 reference materials for implementing Chapter 571 of the Acts of 1986, Education--Libraries and Media Centers in Public Schools--Black History. A listing of 17 publishers is also included. In "The Role of Evaluation in the Library Media Collection Development Process," Jacqueline Mancall discusses reasons for evaluating school library media collections and briefly describes various evaluation methods, including impressionistic approaches, comparison of the collection with an authoritative list, measurement of usage, and bibliographic techniques. Finally, "Weeding: Reassessment of Library Media Collections" discusses the reassessment of collections using the general criteria of condition, duplication, age, and use, and presents brief guidelines to be considered when examining each section of a school library media center organized according to the Dewey Decimal Classification System.
