I Ching (YiJing) software, my favorite, I use it every day. The texts and translation are better than many other I Ching-books. Casting a hexagram with this program is extremely accurate! Works better than casting coins. www.sundialler.com Get the demo and see for yourself! It is not expensive too. 
It is not just a divination program, but a translation, literal translation (a bit like Karcher/Ritsema), Chinese version, lexicon with concordance, extensive notes and essays. Good!

  The "Yin-Yang horoscope". Calculate your birth hexagram at http://www.hall-of-man.com/horoscope_indata.asp Seems to have some mistakes, so not all calculations are perfect. Best is to get the book by Sherrill and Chu "The Astrology of I Ching" and to do it yourself! Or follow Harmen's online course - recommended!

Prima beschrijving van de trigrammen op "Terrestre"

  The "Lun Yu" (Confucian Analects) in English. http://www.confucius.org/lunyu/lange.htm For the Dutch version: change lange into langd.

  Website of Gregory Whincup: The I Ching on the Net I love his book 'Rediscovering the I Ching' very much. It was the first one which gave me a wider view on the hexagrams. Leaving the narrow path of tradition.

  Searching for an out of print I Ching - or any other book? On this site you find all the addresses. Fill in author and/or title just once and search them all in minutes. A super-site, deserves an award! www.trussel.com/f_books.htm

  Ralph Abraham started writing a book about the Yi. He never finished it, but the part he has done is at www.yarrowstalk.org/iching  Very good information about its origins. About older I Chings: the Lien Shan, Kuei Tsang and Chou I in chapter 3, with a part of hex.25 the way it was in the Lien Shan: about the pest! 
Mm, seems not to work anymore. If it still doesn't open next week, I will remove the link.

  In the National Geographic an article about the oldest Chinese characters ever found.

  One of my favorite websites is  http://www.onlinegraduateprograms.com/resources/master-of-arts-sociology-guide-to-world-religions/  a wonderful site full of beautiful old texts. The Bhagavad Gita, the Bible, Gnosticism, Zoroaster, Taoism and much more.

  I came across a big interesting site, 'Windsor castle', where one can stay for ages without becoming bored one second. http://oaks.nvg.org/index.html There are innumerable different things, but there is also the translation of the I Ching by Wilhelm and by Legge. Laotze, Chuangtze and more, more, more.

  If you are looking for any book about I Ching, Taoism, Zen and so on, and you need some information, go to www.au-bout-du-monde.nl  As far as I know, it was the very first bookshop with this kind of books. Even the Dalai Lama orders books there. They know everything, even if you search for some vague information you have seen somewhere in some book, they very often can name the book, the writer or the subject.

  Makoto Ogino: http://homepage2.nifty.com/index_Z/ It is about the I Ching in Japan, you find here a lot of wonderful information about the I Ching and many other related systems. Extremely good and extensive.

 Yale University Press and the China International Publishing Group have begun a huge encyclopedia on Chinese culture: http://www.yale.edu/yup/china.html
