World Book Encyclopedia, American encyclopaedia designed to meet the curriculum needs of elementary through high-school students. It is produced by World Book, Inc., which is headquartered in Chicago.
The World Book was first published in 1917 and revised annually from 1925. Its title was later shortened to World Book. Filling 22 volumes, this specific-entry print reference work emphasizes geography and biography and gives broad treatment to such subject areas as business, psychology, government, energy, ecology, and criminology. Contributors include authorities in the physical, biological, and social sciences and other fields. World Book features thorough cross-references, and lists of related articles are included at the end of entries on major subjects. A general index is augmented by reading and study guides on important subjects. Illustrations and maps are extensive and of high quality. Print yearbooks are issued.
By 1995 World Book had become available in two CD-ROM versions, and by 1999 it was available online. World Book, Inc., subsequently released numerous digital products while continuing to publish its print edition.
