Looking up to see how I could most appropriately direct you to copies of the book Zen Flesh, Zen Bones, I found this reference at http://www.zenguide.com/zenmedia/zen_buddhism_recommended_books.cfm?startrow=11&selected=12
16. ZEN FLESH, ZEN BONES: A COLLECTION OF ZEN AND PRE-ZEN WRITINGS by Nyogen Senzaki, Paul Reps (compilers) Publisher: Shambhala Publications, Inc. (ISBN #: 1570620636, Paperback, 285 pp, January 1994)
Here, in one volume are four original sources for Zen 101: Zen Stories, The Gateless Gate, Bulls, and Centering Together serve as a desirable volume of source readings for one already familiar with Zen. For the reader not familiar with Zen, this is an ideal introduction.
