"Captain Underpants and the Perilous Plot of Professor Poopypants." "Captain Underpants and the Wrath of the Wicked Wedgie Woman." "Captain Underpants and the Farty Fight for Free Speech." Okay fine, I made up the last one.

The silly titles of the "Captain Underpants" series lined our bookshelf at home, thanks to my younger brother. As his wiser and worldlier older sister, I wanted nothing to do with such absurdity. It seems some older people, however, have taken greater offense to Dav Pilkey's children's books, their paranoia almost more farcical than the titles themselves.

For the past two years, "Captain Underpants" was the book sought to be censored or banned, according to the American Library Association (ALA).

is an effort the national book community has organized since 1982 to draw attention to the problem of censorship in schools, bookstores, and libraries. The week celebrates so-deemed "harmful" books, which paternalistic forces have tried, sometimes successfully, to take off the shelves.

Beginning in the 1830s until the end of the Civil War, for example, the U.S. postmaster general refused to carry to the South. During the Red Scare, were jailed for alleged ties to communism. In the 1980s, the Reagan administration actually passed a law to end the production of — because heaven forbid the visually impaired be corrupted through their fingers.

Today, teachers and librarians remain under a barrage of paranoid adults attempting to remove material from school curricula and bookshelves. Other censorship advocates have turned to the Internet as their new frontier. And in an age of surveillance, many writers are increasingly engaging in to protect themselves from a snooping government.

Since its inception in 1920, the ÀÏ°ÄÃÅ¿ª½±½á¹û has been at the forefront of the fight against censorship, winning many important victories for free speech along the way.

Whether about an underpants , a troubled , or a civil rights , information and our unfettered access to it is critical for free thought and the health of our democracy.
