Amid a national rise in book bans in school libraries and new laws in some red states that threaten criminal penalties against librarians, a growing number of blue states are taking the opposite approach.

New Jersey joined at least five other states — California, Illinois, Maryland, Minnesota and Washington — that have passed legislation within the past two years that aims to preserve access to reading materials that deal with racial and sexual themes, including those about the LGBTQ+ community.

Conservative groups have led the effort to ban materials to shield children from what they deem as harmful content. In the 2023-24 school year, there were 10,000 instances of book bans across the U.S. — nearly three times as many as the year before, according to a recent report by PEN America, a nonprofit that advocates for literary freedom.
