Banned Books Week is an annual event that celebrates the freedom to read and highlights the importance of access to diverse literature. It takes place in the last week of September and aims to raise awareness about the challenges and censorship faced by certain books in schools and libraries. During this week, various organizations, including the American Library Association, promote discussions and activities that encourage people to explore and advocate for the right to read. The event also features lists of frequently challenged books, showcasing titles that have faced bans or restrictions due to their content.
