In recent years an alarming number of books are being banned in U.S. public school classrooms, libraries, or both.

PEN America’s Index of School Book Bans lists 2,532 instances of individual books being banned, affecting 1,648 unique book titles and 1,261 different authors in one year’s period (July 2021 to June 2022). The American Library Association (ALA) reports that this current trend in 2022 is the highest number of book challenges since the American Library Association began recording this data over 20 years ago. The subject matter of these banned books relates to content on race and racism, gender identities, and sexual content.
