Tao of Jeet Kune Do was compiled posthumously from Bruce Lee's personal notes, some of which were in turn copied from Bruce Lee's personal library of martial arts and philosophical books. Ohara Publications has acknowledged Edwin Haislet, Hugo and James Castello, Roger Crosnier and Julio Castello as original sources. After the book's initial publication, additional passages were discovered to have been sourced from the works of D.T. Suzuki, Eric Hoffer, and other authors.
