Reasons exist for perceptions of school librarians and libraries that may be historic and nostalgic—yet are still powerful—as they may impact decisions made by school leaders, teaching colleagues, and students about the role libraries and librarians play in IB education. After conducting specific research amongst IB school librarians, the chapter outlines that IB documentation exists to identify librarian roles. Librarian pedagogy is recognized, together with a discussion about the impact of the COVID-19 pandemic on school library programs. The chapter takes a premise that school library/ian roles may be invisible or hidden, identifying factors to enable change to greater awareness of the contributions of the school library and the librarian in IB teaching and learning.
