“First presented in 1967 and customarily announced in the spring, the Boston Globe–Horn Book Awards are among the most prestigious honors in the field of children’s and young adult literature. Winners are selected in three categories: Picture Book, Fiction and Poetry, and Nonfiction. Two Honor Books may be named in each category. On occasion, a book will receive a special citation for its high quality and overall creative excellence. The winning titles must be published in the United States but they may be written or illustrated by citizens of any country. The awards are chosen by an independent panel of three judges who are annually appointed by the Editor of The Horn Book.”
