Equitable access to information for all, including underserved populations, is a core value of librarianship. The growing awareness of where this inequality persists has led many professionals to take steps to advance social justice within their institutions, from creating book displays about the Black Lives Matter movement or LGBT History Month to hosting programs by potentially controversial speakers. But while libraries are often well-versed in protecting the right to read books, many lack policies and experience in addressing censorship of resources and services. This resource, from the Assistant Director of the American Library Association's Office for Intellectual Freedom (OIF), uses specific case studies to offer practical guidance on safeguarding intellectual freedom related to library displays, programming, and other librarian-created content. Essential for library directors, administrators, marketers, and programming staff, this title spotlights case studies drawn from public libraries, schools, universities, and government agencies dealing with library displays, artwork, programs, bookmarks and reading lists, social media, and databases; summarizes possible complaints and controversies related to each area; draws connections between the intellectual freedom principles involved and associated legal issues, with relevant court opinions when possible; shares questions to consider when strengthening a library's defenses against censorship; discusses the importance of reporting challenges to OIF, and the professional and institutional support that OIF can provide when challenges arise; and includes key ALA policies on intellectual freedom as appendices. This guide will ensure that libraries are prepared to protect diverse voices from censorship while fostering more inclusive institutions that represent and welcome all people and ideas.
