The Freedom to Read Foundation (FTRF) and the American Association of School Librarians (AASL) have joined the Association of University Presses, Barnes & Noble Booksellers, and Freedom to Learn Advocates in filing an amicus curiae brief that supports the request by several organizations to halt enforcement of the Texas law HB 900 on the grounds that it violates the First Amendment rights of booksellers, publishers, authors, and students. HB 900 would compel a vendor to review and rate all books it has already sold to a Texas school, and any book it wishes to sell to schools in the future.
