Because the written word can be a powerful medium to proclaim knowledge and wisdom, it is important to use God’s standard, His Word, as the measure of truth. Therefore, the library media program endeavors to assist students and teachers in developing important information skills and to discern and to use reliable, accurate and authoritative research resources.”
