Encyclopedias

In 1981 Britannica published its first digital encyclopedia—probably the first digital encyclopedia—and thus began a journey toward becoming an almost totally digital company. Today the Britannica.com Web site and many others published by EB and its divisions serve tens of millions of people around the world. They are updated daily.

When you need fast, reliable information for homework, reports, or just a lingering question, World Book Online is the place to go.
