Nancy Jo Lambert writes: “School librarians across the country are waiting anxiously to find out when their school or school system will get hit with the culture war’s latest favorite weapon: the book ban. Since late 2021, prominent book challenges have appeared in Florida, Missouri, Virginia, Washington, and my home state of Texas, among others—and each week seems to bring more. The reconsiderations themselves don’t bother me as much as the precedent: We’re normalizing the use of school libraries as a battleground in political conflicts that have no place in the classroom.”
