The proposed "Librarian Protection Act" aims to safeguard the integrity of public libraries in New Mexico by prohibiting the banning of library materials. The bill defines key terms such as "ban," which refers to the removal or prohibition of materials not aligned with an approved collection development policy, and "challenge," which denotes attempts to restrict library materials. To be eligible for state funding, public libraries must adopt a written policy that aligns with the American Library Association's Library Bill of Rights, ensuring that materials are not removed based on partisan or doctrinal disapproval or the author's identity.

Additionally, the bill stipulates that political subdivisions cannot reduce funding for libraries that comply with these provisions. It clarifies that while libraries must not ban materials, individuals still retain the right to challenge library materials following established procedures. The act is set to take effect on July 1, 2025.
