Several teachers in a school district in Florida are putting covers over books in their classroom libraries due to a vague but far-reaching law that restricts what kind of content they can share with students.

Several social media posts from teachers in the Manatee County School District show coverings over classroom libraries, accompanied by commentaries from the educators themselves expressing sadness or disgust over the effects of a law, signed by Gov. Ron DeSantis (R-Florida) in March, that they say is forcing them to cover their books.

The law is framed as a way to allow parents to have the right to be part of the decision-making process over what instructional materials are used in classrooms or lessons. However, in reality, the vagueness of the legislation (and other bills like it) allows community members to attack any materials that they claim are inappropriate for children, including stories, books or other media that depict LGBTQ individuals or discuss aspects of Black history that may make them uncomfortable.

Teachers in the district were notified last week that, in order to be in compliance with the law, a certified media specialist in the district had to approve all titles present in school libraries, including in classroom libraries. Educators were advised to remove books if they hadn’t been approved yet.

But because many classrooms have dozens, sometimes hundreds, of titles in their classrooms, teachers have decided to cover their entire book collection up, fearing that if they don’t they’ll be prosecuted. Teachers or librarians in violation of the law can be charged with a felony.
