The Story of Civilization by Will and Ariel Durant is an eleven-volume set of books. It was written over a lifetime, and it totals two million words across nearly 10,000 pages. The series is incomplete: in the first book of the series (Our Oriental Heritage, which covers the history of the East through 1933), Mr. Durant stated that he wanted to include the history of the West through the early 20th century. However, the series ends with The Age of Napoleon since the Durants died before any additional volumes could be completed.
The first six volumes of The Story of Civilization are credited to Will Durant, with Ariel receiving recognition in the acknowledgements. In later volumes, beginning with The Age of Reason Begins, Ariel is credited as a co-author.
