A study conducted by CISSL in Ohio reports that 99.4 percent of students in grades 3 through 12 believe school libraries and their services help them become better learners (Todd, et al., 2004). The Ohio Study, the largest study conducted on the effectiveness of school libraries, surveyed13,123 students and 879 teachers. Their voices clearly tell us that an effective school library, led by a credentialed school librarian, plays a critical role in facilitating student learning and knowledge building. This study was replicated in Delaware with 5,733 students and 408 teachers (Todd, 2006), and in Australia (Hay, 2006) with 6,728 students and 525 teachers. These studies convey a strong and consistent message: School libraries are powerful agents of learning, central to engaging students in the transformation of information into deep knowledge and understanding, and providing them with life skills to continue living, learning and working in an information- and technology-intense world.
