"There is more than one way to burn a book. And the world is full of people running around with lit matches." — Ray Bradbury, "Fahrenheit 451"

This week marks the 31st annual Banned Books Week, the American Library Association's celebration of the freedom to read. Banned Books Week also serves as an important reminder of our ongoing duty to ensure that our government maintains open access to all kinds of ideas and information. Although some may think that censorship is a relic from a bygone age, the urge to suppress seemingly dangerous or offensive thoughts will exist as long as human beings continue to think. Last year, there were 464 reported attempts to ban a particular book from a curriculum or library, and many more go unreported. But today, the specter of book burning extends far beyond the library shelves — as more and more information moves online, Internet filtering has become the 21st century's bonfire.

Since its founding in 1920, the ACLU has opposed censorship in all its forms. From books and radio to film, television, and the Internet, we have consistently fought to make sure Americans have the right to say, think, read, and write whatever they want, without fear of government reprisal. In 1926, we defended H.L. Mencken when he was charged with distributing copies of his banned magazine, American Mercury. In 1952, we won Joseph Burstyn, Inc. v. Wilson (aka the "Miracle Decision"), in which the Supreme Court finally struck down film censorship laws. In 1978, we filed a Supreme Court friend-of-the-court brief challenging the government's power to suppress radio broadcasts of George Carlin's "Seven Words You Can't Say On Television." And in 1997, we won Reno v. ACLU, which held that Internet speech is entitled to full First Amendment protection. And those are just a few of my personal favorites: more of the ACLU's most notable "Banned Book" cases are listed below – and some are from the not-so-distant past.

We are proud of this legacy, but we're not resting on our laurels. In the last five years, we joined in the Supreme Court challenge against the Federal Communications Commission's "fleeting expletive" rule. We successfully challenged the government's ideological exclusion of Professors Tariq Ramadan and Adam Habib from the country's borders. We launched a campaign to prevent public schools throughout the country from filtering LGBT web content. And we continue to challenge the government's use of its surveillance powers in ways that chill individual expression. (See here and here ). We remain passionately committed to the First Amendment values that keep our society open. And we will continue to oppose censorship wherever it rears its ugly head.

The Vietnam Reader, various authors

After a parent complained about passages from "The Vietnam Reader" that included violence and were sexually explicit, a committee in the North Kitsap School District in Washington deleted four readings without opening the discussion to members of the community. ACLU advocacy resulted in the creation of a policy to provide a fairer process for considering book challenges.

Sophie's Choice, William Styron

The Norwalk-La Mirada High School District in California removed "Sophie's Choice" from the La Mirada High School library shelves after a parent complained about sections of the acclaimed novel. When students expressed concerns that their First Amendment rights were being violated, the ACLU wrote a letter to the school district asking that the book be returned to the school library shelves. The book has since been returned.

Harry Potter series, J.K. Rowling

A Zeeland, Mich., school district banned students in grades K-4 from taking the "Harry Potter" books out of the school library and required students in grades 5-8 to obtain parental permission before borrowing them.

After the ACLU sent letters to the public schools, the district formed a committee to review the issue and rescinded the policy.

Ulysses, James Joyce

In one of the organization's most famous cases, the ACLU defended Joyce's "Ulysses" after U.S. Customs officials seized copies of the novel, calling it obscenity "of the rottenest and vilest character." After a decade-long struggle, it was ruled that "Ulysses" was not obscene.
