The National Counsel of Teachers of English has established an annual award for promoting and recognizing excellence in the writing of nonfiction for children. The name Orbis Pictus, commemorates the work of Czech educator Johannes Amos Comenius. His textbook, Orbis Pictus—The World in Pictures, published in 1657 is considered to be the first book actually planned for children. Honor books for this award can be found on the NCTE website: ncte.org/awards/orbispictus
