Written by three big historians with long experience of teaching big history, this is the first college level textbook on big history. It updates the big history narrative, incorporates the core idea of Thresholds of Increasing Complexity, adds further readings and resources, and also chapter questions and many illustrations, maps and diagrams. Nine of the thirteen chapters concern global human history. Available also as an ‘ebook’ and a ‘smartbook’. Additional resources for teaching this text can be found at the Big History Project (www.bighistoryproject.com) and Rich Simon, et al, eds, Teaching Big History (Berkeley, CA: University of California Press, 2015).
