What is a book ban?
A book ban is the removal or restriction of access to a book in a public school or library because a person or group objects to its content. It can be permanent or a “pending review” that pulls the book for months. Either way, it takes the book away from every reader, not just the one who complained.
Key facts
- Public schools recorded 6,870 book bans in the 2024-2025 school year, the most ever, hitting nearly 4,000 different titles (PEN America).
- There have been roughly 23,000 book bans in public schools since 2021 (PEN America).
- Just three states, Florida, Texas, and Tennessee, account for 80% of all bans (PEN America).
- PEN found 81% of the districts banning books sit in or next to a county with a chapter of an organized pressure group (PEN America).
- The Supreme Court ruled in 1982 that schools may not remove library books simply because officials dislike the ideas in them (Island Trees v. Pico).
The word “ban” is sometimes disputed, so it helps to be precise. A parent deciding their own child should not read a book is a personal choice. A school board pulling that book from the shelves so no child in the district can read it is a ban. PEN America counts the second kind: a book removed or restricted for all students after a challenge.
The scale of the bans
Book bans are not spread evenly across the country. They are concentrated in a handful of states where state law and organized pressure have made challenges routine.
Three states drove 80% of all school book bans in 2024-2025.

Florida alone accounted for a third of every book ban in the country. The pattern matters because it shows what drives the bans. Where states passed laws making it easy to challenge books and hard for librarians to refuse, the numbers exploded. Where they did not, more than two dozen states recorded zero bans in the same year.
Who is banning the books
The image of a book ban is a lone parent at a school board meeting. The data tells a different story. Most challenges are coordinated.
PEN America found that 81% of the school districts that banned books sit in or next to a county with a local chapter of an organized advocacy group such as Moms for Liberty. Many challenges are not about a single book. They arrive as lists of 100 or more titles at once, often copied from national campaigns rather than drawn from anyone who actually read them.
What the bans target
The books pulled most often share a pattern. They are by or about LGBTQ people and people of color.
PEN America found that the targeted titles overwhelmingly depict race and racism, LGBTQ identities, or sexual content, and that challengers routinely label any book with an LGBTQ character as “sexually explicit,” whether or not it contains sex. The effect is to erase LGBTQ and Black stories from school shelves under the cover of protecting children.
The most-banned authors are not who you might expect. Horror novelist Stephen King led the 2024-2025 list with 206 bans, followed by young-adult author Ellen Hopkins and fantasy writer Sarah J. Maas. Award-winning books about the Black and LGBTQ experience are pulled alongside them.
What the law says
The Supreme Court has addressed school book removals once, and it drew a line that still governs today.
In Island Trees School District v. Pico (1982), the Court considered a school board that pulled nine books it called “anti-American” and “filthy.” A fractured plurality, led by Justice Brennan, held that school boards “may not remove books from school library shelves simply because they dislike the ideas contained in those books.” It was the first time the Court recognized a student’s right to receive information in a library.
The ruling was splintered and left the edges unclear, which is why book-ban fights still end up in court. But its core survives. A board can weed a book for being worn out or outdated. It cannot pull a book to punish the ideas inside it.
Book banning is not new
The current wave is the largest in U.S. history, but the impulse is old. Censorship has surged before, and the banned books usually outlived the bans. The Comstock Act criminalized “obscene” books in 1873, courts freed Ulysses in 1933, the Supreme Court limited school removals in 1982, and the modern wave began in 2021.
- The Comstock Act A federal law criminalized mailing "obscene" books and material, used for decades to suppress literature.
- Ulysses cleared in court A federal court ruled James Joyce's Ulysses was not obscene, a landmark free-speech win.
- Island Trees v. Pico The Supreme Court barred removing library books just because officials dislike the ideas.
- The modern surge begins Organized campaigns drive school book challenges to levels not seen in generations.
- A record 6,870 bans The most school book bans ever recorded in a single year, concentrated in three states.
- Federal pushback Members of Congress introduce bills to protect school libraries and treat bans as a civil rights issue.

Book banning in America, from Comstock to today: 1873 — The Comstock Act (A federal law criminalized mailing "obscene" books and material, used for decades to suppress literature.). 1933 — Ulysses cleared in court (A federal court ruled James Joyce's Ulysses was not obscene, a landmark free-speech win.). 1982 — Island Trees v. Pico (The Supreme Court barred removing library books just because officials dislike the ideas.). 2021 — The modern surge begins (Organized campaigns drive school book challenges to levels not seen in generations.). 2024-25 — A record 6,870 bans (The most school book bans ever recorded in a single year, concentrated in three states.). 2026 — Federal pushback (Members of Congress introduce bills to protect school libraries and treat bans as a civil rights issue.).
History offers a consistent lesson. The books targeted in one generation, from Ulysses to Slaughterhouse-Five to Beloved, are often the ones the next generation assigns in class. Bans rarely erase a book. They advertise it.
How the bans are being fought
The surge has produced a response, in the courts, in statehouses, and in Congress. The reader has more leverage here than the headlines suggest.
In Congress, Rep. Ayanna Pressley introduced the Books Save Lives Act (H.R. 8235), which would require schools to keep diverse collections and treat the targeted removal of books about a group of people as a civil rights violation. Rep. Raúl Grijalva and Sen. Jack Reed introduced the Right to Read Act to fund and protect school libraries, and a third bill, the Fight Book Bans Act, would help districts cover the cost of defending challenges.
States are moving too. Several have passed “freedom to read” laws that set clear review processes and protect librarians from prosecution. And local pushback works. When parents, students, and librarians show up to the same board meetings the campaigns target, books are often returned.
What a book ban is not
Not every decision about a book is a ban, and overusing the word weakens the case against real ones.
The line between curating a collection and banning a book.
| A book ban | Not a book ban |
|---|---|
| Removing a book for all students because of its ideas or identity content | A parent choosing what their own child reads |
| Pulling titles from an organized list of challenges | A librarian weeding a damaged or outdated copy |
| Restricting access district-wide after a complaint | Shelving a book by age or reading level |
| "Pending review" that keeps a book off shelves for months | A teacher choosing one novel over another for a class |
Schools make legitimate choices about what belongs in a collection every day. The difference is the reason. Removing a book because it is falling apart is curation. Removing it because it features a gay character is a ban.
Frequently asked questions
Are these books illegal to own or sell? No. A book ban in this context means removal from a public school or library. The same books are almost always available to buy, and bans often increase their sales.
Is “ban” the right word if a book is only under review? PEN America counts a book as banned when it is removed or restricted for all students after a challenge, including long “pending review” periods that keep it off shelves. The reader loses access either way.
Can parents still object to a book? Yes. A parent can always decide what their own child reads, and most schools have an opt-out process. The dispute is about removing a book for everyone, not about a single family’s choice.
Do book bans actually stop kids from reading the books? Rarely. Banned titles routinely see sales spikes, and libraries outside the district report higher demand. The lasting effect is on the kids who needed to find that book on a shelf and could not.
What you can do
-
Tell Congress to protect school libraries. Ask your representative to co-sponsor the Books Save Lives Act (H.R. 8235), which keeps collections diverse and treats targeted removals as a civil rights violation. Use the letter below.
-
Show up to school board meetings. Organized campaigns count on empty rooms. When parents, students, and teachers attend the same meetings and speak for the books, boards often reverse course. Check your district’s agenda for “library materials” or “reconsideration” items.
-
Support the librarians. Many bans succeed because a single librarian is left to face an organized challenge alone. Back Unite Against Book Bans and your local Friends of the Library, and thank the librarians doing the work.
-
Read the banned books. Check the PEN America Index and read what is being pulled. Buying and discussing a challenged book is the simplest answer to a ban.
-
Write your representative about the Books Save Lives Act and the freedom to read. Use the letter below.
