In Wyoming, a county prosecutor's office considered charges against library employees for stocking books like "Sex Is a Funny Word" and "This Book Is Gay."
In Oklahoma, a bill was introduced in the state Senate that would prohibit public school libraries from keeping books on hand that focus on sexual activity, sexual identity or gender identity.
In Tennessee, the McMinn County Board of Education voted to remove the Pulitzer Prize-winning graphic novel "Maus" from an eighth-grade module on the Holocaust because of nudity and curse words.
Parents, activists, school board officials and lawmakers around the country are challenging books at a pace not seen in decades. The American Library Association said in a preliminary report that it received an "unprecedented" 330 reports of book challenges, each of which can include multiple books, in the fall.
"It's a pretty startling phenomenon here in the United States to see book bans back in style, to see efforts to press criminal charges against school librarians," said Suzanne Nossel, chief executive of free-speech organization PEN America, even if efforts to press charges have so far failed.
Such challenges have long been a staple of school board meetings, but it isn't just their frequency that has changed, according to educators, librarians and free-speech advocates — it is also the tactics behind them and the venues where they play out. Conservative groups in particular, fueled by social media, are now pushing the challenges into statehouses, law enforcement and political races.
"The politicalization of the topic is what's different than what I've seen in the past," said Britten Follett, chief executive of content at Follett School Solutions, one of the country's largest providers of books to K-12 schools. "It's being driven by legislation; it's being driven by politicians aligning with one side or the other. And in the end, the librarian, teacher or educator is getting caught in the middle."
Among the most frequent targets are books about race, gender and sexuality, like George M. Johnson's "All Boys Aren't Blue," Jonathan Evison's "Lawn Boy," Maia Kobabe's "Gender Queer" and Toni Morrison's "The Bluest Eye."
