A federal district judge ordered the Miami-Dade School Board to put a children’s book about Cuba back on the shelves immediately until the case goes to trial. The judge, Alan S. Gold, issued a preliminary injunction in favor of the American Civil Liberties Union of Florida, which filed a lawsuit challenging a school board decision to remove the book, “Vamos a Cuba,” and its English version, “A Visit to Cuba.” The board voted to ban the book last month after a parent said it painted a deceptive picture of life in Cuba.
