Leaders have taken works as seemingly innocuous as the popular children’s picture book “In the Night Kitchen” by Maurice Sendak off the shelves, closed library board meetings to the public and named Wallace the vice chair of a new library board stacked with conservative appointees — some of whom did not even have library cards.

With these actions, Llano joins a growing number of communities across America where conservatives have mounted challenges to books and other content related to race, sex, gender and other subjects they deem inappropriate. A movement that started in schools has rapidly expanded to public libraries, accounting for 37 percent of book challenges last year, according to the American Library Association. Conservative activists in several states, including Texas, Montana and Louisiana have joined forces with like-minded officials to dissolve libraries’ governing bodies, rewrite or delete censorship protections, and remove books outside of official challenge procedures.

“The danger is that we start to have information and books that only address one viewpoint that are okayed by just one certain group,” said Mary Woodward, president-elect of the Texas Library Association.
