Prohibits book banning in public libraries and schools; authorizes withholding of State aid for noncompliance.

New Jersey's A4120 prohibits public libraries (including county, regional, and municipal types) and school districts from banning or restricting access to books based on political or religious views. It requires these entities to adopt the American Library Association's Library Bill of Rights or a similar policy explicitly banning such restrictions. Noncompliant libraries risk losing state library aid, while noncompliant school districts could face withheld education funding. The law explicitly states it does not require libraries or schools to purchase specific books for their collections.
