The mission of the library media program is to ensure that students and staff are effective users of ideas and information. This mission is accomplished:

• by providing intellectual and physical access to materials in all formats
• by providing instruction to foster competence and stimulate interest in reading, viewing, and using information and ideas
• by working with other educators to design learning strategies to meet the needs of individual students.
