The World Almanac is a classic statistical reference tool. With age-specific resources, users can choose the right resource for their needs. Resources to help children develop online research skills are somewhat hard to find; the World Almanac offers many kinds of support material in addition to basic searching. The Kids Elementary edition, in addition to providing illustrated articles written for young children, includes videos, games, and other resources.
