This document discusses the importance of school libraries and licensed librarians/library media specialists. It notes that students and teachers are at a disadvantage without access to these resources, as they are less likely to learn important skills and understand digital citizenship. The document also highlights research showing that student achievement increases by 10-20% when schools have libraries staffed by certified librarians. However, it notes that many schools nationwide lack these resources, with over 75% of schools in Philadelphia not having a librarian or library.
