A children’s story about two gay penguin fathers was named this week as one of the books most likely to be censored in public school libraries.

On Monday, the American Library Association released its annual list of book challenges recorded by ALA’s Office for Intellectual Freedom.

The association noted that 80 percent “of the 2014 Top Ten List of Frequently Challenged Books reflect diverse authors and cultural content.”

The prize-winning autobiographical novel “The Absolutely True Diary of a Part-Time Indian” by Sherman Alexie came in at number one for being “anti-family” and having “offensive language” and “sex education.”

The graphic novel “Persepolis” by Marjane Satrapi was number two. Political viewpoint was cited as one of the reasons. The picture story “And Tango Makes Three” by Justin Richardson and Peter Parnell about two gay penguins received the third-most complaints for having anti-family and homosexual themes.

Other books most likely to be censored included Toni Morrison’s “The Bluest Eye,” Robie Harris’ “It’s Perfectly Normal,” Khaled Hosseini’s “The Kite Runner,” and Jaycee Dugard’s “A Stolen Life.”

In past years, the “Harry Potter,” “Twilight,” and “The Hunger Games” novels were often challenged. Older books like “I Know Why the Caged Bird Sings” and “To Kill a Mockingbird” also often make appearances on the list.
