Some conservative states try to police readings, discarding books they accuse of promoting homosexuality, progressive ideologies, or being too shocking. Classics, such as the works of Toni Morrison or the graphic novel about the Holocaust "Maus", by Art Spiegelman, were targeted.

This phenomenon "damages democracy, deprives students of very important resources and can contribute to the stigma and isolation experienced by LGBTQ+ communities and others," says the White House. The White House has appointed a "coordinator" to fight against these bans.
