The group found that from July 2024 to last June, 3,743 unique titles were removed from school libraries and classrooms nationwide—and 1,102 of them were "educational or informational books for young people—textbooks or reference texts on a wide range of subjects, history books, biographies, and autobiographies."
Although the majority of banned titles were still fiction, such as Fahrenheit 451 by Ray Bradbury and The Hunger Games by Suzanne Collins, the share of "fiction titles dropped from 85% to 69% of all banned titles, while nonfiction rose from 14% to a startling 29% of all banned titles," according to the analysis.
"This marked impact on books anchored in scientific and historic facts, real events, and real people represents something new and distinctive about the trajectory of book bans in public schools," the report states. "As nonfiction titles are not always the targets of efforts to remove books, that books on ancient Egypt, the digestive system, and self-help for teens, to name a few examples, are impacted by censorship signals an alarming spread of book bans that ignore the educational value of texts and books."
Targeted "nonfiction titles are wide-ranging," the report notes, "from memoirs such as Night by Elie Wiesel to biographies such as RuPaul by Maria Isabel Sánchez Vegara, alongside historical and educational or informational books such as Aztec, Inca & Maya by Elizabeth Baquedano and Challenges for LGBTQ Teens by Martha Lundin."
Flagging this "embrace of anti-intellectualism" in a statement about the new report, Kasey Meehan, director of PEN America's Freedom to Read program, said that "it is another example of how censorship sweeps broadly, leading to removals of all kinds of books, in its efforts to sow fear and distrust in our public education system."
Like the previous academic year, "realistic/contemporary and dystopia/sci-fi/fantasy remain the dominant genres banned," the publication highlights. "But of note, educational/informational titles grew from 5% of all titles in 2023-24 to 13% of total titles banned in 2024-25, or nearly 500 unique titles."
Among the nonfiction titles banned, "52% contained themes of activism and social movements, the most commonly banned topic within nonfiction titles," the report says. "Whether #WomensMarch: Insisting on Equality by Rebecca Felix or IntersectionAllies: We Make Room for All by Chelsea Johnson, LaToya Council, and Carolyn Choi, and illustrated by Ashley Seil Smith, this literature is crucial in the education of young people. These books can encourage readers to challenge the status quo and resist injustice."
Freedom to Read program assistant and report co-author Yuliana Tamayo Latorre said that removing books on these topics "silences the voices of marginalized communities and erode[s] their ability to take action amid rising authoritarian tactics by our government and attacks on free speech."
The most common theme across all banned books was nonsexual violence. This was a theme in 57% of the targeted titles, and they addressed topics including "war, gun violence, natural disasters, domestic violence, human trafficking, slavery and genocide, physical fighting, and more."
Other key themes included death and grief (48%), empowerment and self-esteem (39%), LGBTQ+ topics and metaphors (36%), consensual sexual experiences (34%), mental health disorders (29%), verbal or emotional abuse (28%), and substance use and/or abuse (27%).
There was an increase in banned titles with themes of empowerment and self-esteem, up from 31% in 2023-24.
"Fictional titles with themes of empowerment include Flor Fights Back: A Stonewall Riots Survival Story by Joy Michael Ellison and illustrated by Francesca Ficorilli, and The Moon Within by Aida Salazar," the report says. "To remove these books from classroom and library shelves means revoking access to books that students may rely on for personal and emotional development."
There is an entire section of the report about "erasing people" that examines trends in the identities of characters in banned books. Of all the targeted titles, 44% featured people of color, 39% had LGBTQ+ characters, 19% included transgender or genderqueer individuals, and 10% involved those who are neurodivergent or disabled.
Trump and other leading Republicans have embraced and advanced campaigns against diversity, equity, and inclusion (DEI). PEN America acknowledged that such efforts "have contributed to restrictions and removals on books with people of color and mirror efforts to suppress curriculum on Indigenous history, Black history, Asian American and Pacific Islander stories, and Latine and Hispanic contributions."
Another section of the report addresses a major "discrepancy between the titles impacted by book bans and the justifications made to ban books. Book banners have long cited 'pornography' and 'sexually explicit' material in literature to justify book challenges. Claims that these books contain 'explicit' or 'obscene' content grossly misrepresent the materials."
That section points out that 19% of last year's banned titles contained sexual violence—and "according to RAINN, 1 in 9 girls and 1 in 20 boys under 18 experience sexual abuse or assault. With so many of these titles banned since 2021, it is possible that some young people who have experienced sexual violence no longer have access to books that could help them."
"Books containing experiences of sexual violence include The Nickel Boys by Colson Whitehead, winner of the 2020 Pulitzer Prize for Fiction, set in a 1960s Southern juvenile reform school, and Laurie Halse Anderson's memoir Shout, a call to action for sexual abuse and trauma survivors in the wake of the #MeToo movement," according to PEN America.
The group's report came just a few weeks after a similar annual publication from the American Library Association, which details challenges to at least 4,235 unique titles in 2025, resulting in bans on at least 5,668 books and restrictions on another 920 works.
"In 2025, book bans were not sparked by concerned parents, and they were not the result of local grassroots efforts," noted Sarah Lamdan, executive director of the association's Office for Intellectual Freedom. “They were part of a well-funded, politically driven campaign to suppress the stories and lived experiences of LGBTQIA+ and BIPOC individuals and communities."
