From the big bang to the 21st century, the renowned Berkshire Encyclopedia of World History provides an integrated view of human and universal history. In its 580 articles, eminent scholars examine environmental and social issues by exploring connections and interactions made over time (and across cultures and locales) through trade, warfare, migrations, religion, and diplomacy. The Berkshire Encyclopedia of World History has become the standard reference for world history teaching across the United States. Berkshire's ongoing work with the original group of authors and with dozens of world history teachers (who embraced not only the Encyclopedia but a spin-off classroom publication, This Fleeting World by David Christian) has helped to shape the new, expanded, updated, and much enhanced second edition.
