The Facts On File World News Digest database covers 1940 to the present, with weekly updates. It includes a live Reuters® newsfeed, updated hourly. Special "Top Stories" timelines deliver, decade by decade, listings linked to original coverage of top news stories back to October 1940. Original feature essays created for the online version, such as Country Profiles, Key People, Key Events, and Key Issues — plus primary documents, editorial cartoons, and a selection of newspaper editorials — round out and link to the information in the World News Digest, and place the events covered in historical perspective. Special "Ahead In Time" and "Back In Time" links allow researchers to follow the thread of one story as it develops from week to week. Photos, maps, charts, and graphs are also included in this authoritative reference database.
