School Libraries Work! seeks to empower librarians, classroom teachers, school and district leaders, policy makers, parents, and communities by arming them with the most powerful research-based frameworks, recommendations, and support for school library programs. This compendium updates and builds upon the 2008 edition, reinforcing the most relevant themes from that report while highlighting recent research at both the national and state levels. At a national level, this report highlights key findings from the National Center for Literacy Education, along with the School Library Journal's (SLJ) national analysis of the relationship between librarian staffing and the National Assessments of Educational Progress (NAEP) fourth-grade reading scores.
