Stemming from an American Association of School Librarians (AASL) Chapters concern, the 2018 American Library Association (ALA) Emerging Leaders team was charged with creating a guide for AASL to support school librarians in addressing challenges related to censorship and patron privacy issues, particularly with LGBTQ+ materials. "Defending Intellectual Freedom: LGBTQ+ Materials in School Libraries" is more than a collection of resources. This guide offers ways to use the Shared Foundations from the AASL Standards -- "Inquire," "Include," "Collaborate," "Curate," "Explore," and "Engage" -- to build LGBTQ+-inclusive library instruction, collections, and spaces. Activities in each section make this a valuable tool for professional development. This guide is a great example to any practitioner about how they can use the AASL Standards as a lens to address ANY school library issue!
