AbstractBook banning is a topic covered in many US history classrooms. Students learn that in the first decades of the twentieth century, fights over the teaching of evolution led to restrictions on science texts. Meanwhile, fears about the spread of communism sparked campaigns to limit access to “subversive” ideas. Well into the 1960s, textbooks usually explain, Americans remained at odds about what schools should be free to teach.What’s old is new, it seems. And tomorrow’s textbooks will have to be updated with stories from the present. As this issue goes to press, conservative groups across the United States have sought to remove hundreds of titles from schools and libraries. Such attempts range from challenges filed by individual parents—often inspired by the list curated on BookLooks.org—to statewide legislative efforts to recall books from schools. Thousands of books have been removed from libraries and classrooms, and the chilling effect has led cautious educators to self-censor even further.For this policy dialogue, the HEQ editors asked Adam Laats and Kasey Meehan to discuss book banning in the US, focusing particularly on the motivations of groups seeking to limit what young people can read. Adam Laats is a professor of education and history at SUNY Binghamton. A leading scholar of conservative activism in education, he is the author of several books including The Other School Reformers (Harvard University Press, 2015) and Fundamentalist U (Oxford University Press, 2018). Kasey Meehan is the director of the Freedom to Read program at PEN America, where she leads initiatives to protect the right of students to freely access literature in schools. Founded in 1922, PEN America is the largest of the more than one hundred centers worldwide that make up the PEN International network. PEN America works to ensure that people everywhere have the freedom to create literature, to convey information and ideas, to express their views, and to access the views, ideas, and literatures of others.HEQ policy dialogues are, by design, intended to promote an informal, free exchange of ideas between scholars. At the end of the exchange, we offer a list of references for readers who wish to follow up on sources relevant to the discussion.
