As librarians know, book challenges have risen exponentially over the last three years. Prior to 2020, challenges would typically originate from the occasional community user, however, they have now become politicized and have expanded to contentious board meetings, local and even statewide legislation, sometimes backed by national groups. The uptick in book challenges coincided with the increased mention of “Critical Race Theory” by media and politicians. Most of the books challenged are diverse books. This poster, part of a larger research study, will showcase the literature review analyzing and contextualizing the recent rise in book challenges; focusing on a history of censorship in libraries, the need for diverse books, and libraries and social justice. This poster will also provide a QR code link to the aforementioned study which will examine New Jersey public librarians’ and New Jersey school librarians’ morale after experiencing a book challenge.
