One of my favorite books on the history and cultural background of the Zhou Yi (and later Yi Jing).

I agree with this comment from Religious Studies Review that is quoted on the back cover:

'For once, a publisher's cover blurb is justified in hailing a book as "the most significant contribution of its kind in the twentieth century." This is a monumental scholarly exploration of the I-ching (Yijing, "book of Chages", originally known as the Chou-I/Zhouyi). Virtually every aspect of the Zhouyi and its history, including Western interpretations, is well covered. . . . Rutt's well-documented analyses makes this book mandatory reading that belongs in all collections.'
