Librarian Allison Escoto writes: “Intellectual freedom is now—and will likely always be—a necessary topic for librarians to examine. If every book has its reader, most books will also have a challenger. In addition to considering banned books in schools and libraries, intellectual freedom issues are so closely tied to social justice that librarians often need both a foundational understanding of the topic as well as practical guides, and perhaps a standout example of a banned book, to navigate the often-muddy waters of intellectual freedom in libraries.”
