Banned Books Week is the annual celebration of the freedom to read. The event is sponsored by a coalition of organizations dedicated to free expression, including American Booksellers Association; American Library Association; American Society of Journalists and Authors; Association of University Presses; Authors Guild; Comic Book Legal Defense Fund; Foundation for Individual Rights in Education (FIRE); Freedom to Read Foundation; Index on Censorship; National Coalition Against Censorship; National Council of Teachers of English; PEN America; People For the American Way Foundation; and Project Censored. It is endorsed by the Center for the Book in the Library of Congress. Banned Books Week also receives generous support from DKT Liberty Project and Penguin Random House.
The American Library Association condemns censorship and works to ensure free access to information. Every year, the Office for Intellectual Freedom (OIF) compiles a list of the Top 10 Most Challenged Books in order to inform the public about censorship in libraries and schools. The lists are based on information from media stories and voluntary reports sent to OIF from communities across the U.S.
