The American Booksellers Foundation for Free Expression is the bookseller's voice in the fight against censorship. Founded by the American Booksellers Association in 1990, ABFFE’s mission is to promote and protect the free exchange of ideas, particularly those contained in books, by opposing restrictions on the freedom of speech; issuing statements on significant free expression controversies; participating in legal cases involving First Amendment rights; collaborating with other groups with an interest in free speech; and providing education about the importance of free expression to booksellers, other members of the book industry, politicians, the press and the public.

The ABFFE website is home to resources to help stores exercise and display their commitment to free expression rights; information and materials for “Banned Books Week,” held in late September every year; and other First Amendment oriented programs like the “Kids Right to Read Project.” Booksellers may also purchase tickets and art for the Annual Children's Book Art Silent Auction to benefit ABFFE.

ABA members are encouraged to join and support ABFFE with a yearly tax-deductible contribution, which can be made during the ABA renewal process, or directly with ABFFE.
