A new report from PEN America found that 3,743 unique titles were removed from at least one school library or classroom during the 2024–2025 school year. “In the last school year, we found a surge in the banning of nonfiction titles. We documented bans on over 1,100 unique titles that are educational or informational books for young people—textbooks or reference texts on a wide range of subjects, history books, biographies, and autobiographies.” The most common topics in banned titles included violence, death and grief, and empowerment and self-esteem.
