McGhee (educational leadership, Texas State University-San Marcos) and Jansen (information science, Texas State University-San Marcos) draw on the professional literature, plus site visits and interviews, to help principals understand the importance of a successful library media program and its influence on students and teachers alike. They describe the overarching philosophy guiding the practice of principals and library media specialists, look at best practices in school library services, and discuss the principal's role in hiring, budgeting, and supervision of the library media program.
