World Book has developed 3 new Digital Libraries — Early Peoples, Living Green, and Inventions & Discoveries — to act as an interactive complement to their newest print reference sets. Each digital library includes all the content from the print set, PLUS animations, videos, interactive activities, Web sites, lesson plans, and links to encyclopedic content. The libraries are designed to appeal to those learners who do well in an interactive environment.

And you can try all three here for free, through July 6th —
