Since then, more than 11,300 books have been challenged, organizers have said. The ALA says there were 307 challenges to books recorded just in 2013, and many more go unreported.

“People challenge books that they say are too sexual or too violent. They object to profanity and slang, and protest against offensive portrayals of racial or religious groups – or positive portrayals of homosexuals,” the ALA said in 2010. “Their targets range from books that explore the latest problems to classic and beloved works of American literature.”

Among the events in the area for Banned Books Week this year is a series of readings by Kevin Pyle and Scott Cunningham, authors of the docu-comic “Bad for You: Exposing the War on Fun.” The authors noted that there was a time within the U.S. when comic books were burned.

The authors were also to talk about “how scary old fairy tales once were, as well as what keeps getting Harry Potter books banned (hint, it has something to do with the devil,)” organizers said.

Pyle and Cunningham appeared Monday at the Hamilton Grange Library in Harlem, and will also speak at 3 p.m. Saturday at the New York Public Library Main Branch at Fifth Avenue and 42nd Street.

Meanwhile, New York-based publishing firm Pantheon Books was posting original pieces of art and quotes from graphic novelists regarding book banning on its Tumblr page every day this week.

Events were also held or planned in Nyack and Monticello, and upstate in Plattsburgh, Canastota and Syracuse; as well as Newark, Cherry Hill and Succasunna in New Jersey; and Southport in Connecticut.
