Kurt Erickson writes: “Missouri Secretary of State Jay Ashcroft, who is a likely candidate for governor in 2024, submitted a proposed rule change that would establish a certification requirement for libraries receiving state funds and institute measures to protect minors from what he calls ‘non-age-appropriate materials.’ Under the plan, public libraries would have to adopt policies to determine what material is appropriate for certain ages. And the proposed rule says state money could not be used to purchase or acquire inappropriate materials in any form that appeal to the ‘prurient interest of a minor.’ The rule is in a review period that will last through December 15.”
