A good book to start with that deals mosly with three coin divination
and is easy to under stand and use is one by Stephen Karcher it is probally still in print. It teachs with out being tedious!
Also there is the fortune tellers I ching which I procured at arare and used boob store and to top it off The  IChing Work book by MONDO SECTER which I am more than reassonablr sure is still in print.
 Project guttenberg has free E-Books of all the Chinese classics including
the I Ching. Some of these books explain how to use wood sticks also
nine coins ,but the  three coin method has been around a lond time and is very satisfying!  Check out your local used and new book shops or the
electronic book site above Project Guttenberg it is free!)

Just to re-iterate what some of you have already said....

The best place to start is with a fairly straight translation of the Yi Jing (sorry, I prefer using pinyin to wade-giles - its just how i learned chinese).

The Richard Wilhelm translation is what I started with, and it is a relatively authoritative and good translation. But remember that for English-speakers, you are reading an English translation of a German translation of a modern Chinese translation of ancient Chinese texts....

Having said that, Wilhelm's translation of the Chinese is somewhat dated now, and his own biases come through when you are familiar with the pitfalls of translating Chinese concepts into Western words.

Thomas Cleary has done some very good work in translating ancient Chinese spiritual/philosophical texts - most of his stuff is published by Shambhala Publications. He's released a translation of the Book of Changes called "The Taoist I Ching" (note wade-giles translation), and it is a complete translation of a 18/19th-Century translation/commentaries of Daoist adept Liu I-Ming.

The best thing about this book is the Daoist nature of the Hexagrams, thus more personal and mystical - whereas Wilhelm's are inherently Confucian in nature and the advice is more general, and was used to assist in the governance of the State. This is the fundamental difference between Confucianism and Daoism - the former placed emphasis on the individual's relationship to the community, whereas the latter's emphasis was on the individual's relationship to the Divine.

The Yi Jing is a powerful tool for those of us interested in all things 'mystical' and a good way to learn to live "with the Dao"....

My first I Ching book was Richard Wilhelm's translation, however my favorite I Ching reference is "The Book of Unchanging Truth" by Hua Ching Ni, a living Taoist master. It is extremely informative, with very clear judgements of the hexagrams.

I Ching The No 1 Success Formula by Christopher MARKERT  It explains the meanings in modern terms  which makes it easier to understand.
