District officials in Duluth, Minnesota, schools have removed “To Kill a Mockingbird” and “The Adventures of Huckleberry Finn” from the required reading list because of racial slurs in the books. Michael Cary, the district’s director of curriculum and instruction, said the books will still be optional reading and available in the school libraries, but they’ll be replaced next year by other books that touch the same topics without language that makes students uncomfortable.

“We felt that we could still teach the same standards and expectations through other novels that didn’t require students to feel humiliated or marginalized by the use of racial slurs,” Cary said.

While administrators said that no single incident prompted the reading list change, there have been complaints about the books’ use of a racial slur in the past.

The president of the local chapter of the NAACP praised the district’s decision.

“There are a lot more authors out there with better literature that can do the same thing that does not degrade our people,” Stephan Witherspoon said. “I’m glad they’re making the decision and it’s long overdue, like 20 years overdue.”

“To Kill a Mockingbird” and “The Adventures of Huckleberry Finn” had been required reading in Duluth’s ninth- and 11th-grade English classes.

Other school systems, including Virginia, pulled the books as well.
