Harcourt, Brace, Jovanovich is a U.S. publishing firm, and one of the world's largest publishers of textbooks. As such, it has often been involved in debates about public school curriculum in such controversial areas as the dispute between advocates of evolution and creationism. Critics of different stripes have accused it both of pushing evolution and liberalism and political correctness in an effort to win the lucrative California market and conversely of being reactionary in an effort to win the similarly-sized Texas market; these two states are considered to be crucial in textbook development because they constitute the two single largest U.S. markets for such books.
HBJ is also well known as the publisher of the "Harbrace Handbook" of English usage and as the one-time owner of the SeaWorld family of theme parks.
