The map above comes from from PEN America, which tracks book bans and fights censorship in public schools and libraries across the country.

Here’s how they defined a ban:

PEN America defines a school book ban as any action taken against a book based on its content and as a result of parent or community challenges, administrative decisions, or in response to direct or threatened action by lawmakers or other governmental officials, that leads to a previously accessible book being either completely removed from availability to students, or where access to a book is restricted or diminished, either temporarily or permanently.
