Missouri public libraries must certify that they have policies in place that put parents in charge of what their children read and see.

The most difficult part of the new rule is allowing parents to challenge the aged designation of any item in the library. Some libraries are receiving lists of 100 or more books and challenges overall are increasing, Moeller said.
“Most of the items being included in these lists relate to identity, race or sexual orientation,” she said. “What we really seeing is the ones that relate to identity are being called ‘inappropriate.’”
