I'd like to acknowledge Richard Wilhelm's and Cary F. Baynes translation "I Ching: Or, Book of Changes" [3rd. ed., Bollingen Series XIX, (Princeton NJ: Princeton University Press, 1967, 1st ed. 1950)], James Legge's translation "I Ching : The Sacred Books of China : The Book of Changes" [Dover Publications, 2nd ed. 1975] and Larry Schoenholtz's "New Directions in the I Ching: The Yellow River Legacy" [Seacaucus NJ: University Books Inc., 1975, 1st ed. 1975] for inspiring me to write this script.

An excellent explanation of Larry Shoenholtz's insights for consulting the I Ching (which I've used in this script) can be found at Frank Szot's webpage The Method of 64 for I Ching.

Another discussion of the probabilites behind both the yarrow stalk and coin tossing methods, by Stuart Anderson, can be found at http://www.mension.com/probab1.htm.

I also owe a thanks to Steve VanDevender for his markup of the hexagrams. He also offers a reading, as well as a substitute for the UNIX [BSD 4.2/3/4] ching(6) script.

For an exhaustive directory of on-line I Ching resources, I recommend:

Here's an interesting book by George Rabe, called The I Ching, A 3000 Year Old Digital Computer, about the source of the I Ching:
