Ideas are powerful. That’s why intellectual freedom is protected by the First Amendment — and it's also why sometimes governments try to suppress them. A government that polices what we read polices our thoughts. For nearly 100 years, the ACLU has fought to make sure Americans have the right to read what they want. Despite our many victories, there are still misguided attempts to ban books. The American Library Association keeps track.

But you can’t keep a good book down.
