Schiff, J.L. 2008. Cellular Automata: A Discrete View of the World.John Wiley & Sons.
A readable introduction to cellular automata and their applications.
Wolfram, S. 2002. A New Kind of Science. Wolfram Media. A very ambitious book trying to demonstrate in detail (the book contains 1,197 pages) that the
entire universe around us (e.g., biological, physical, and computational phenomena) could be and should be considered as cellular automata. While the approach of the author is a matter of heated discussion, the book is thoughtprovoking and contains many interesting examples.
Ilachinski, A. 2001. Cellular Automata: A Discrete Universe. World Scientific Publishing. A detailed (approximately 800-page) and technical exposition of
cellular automata. Includes detailed discussions of various theoretical techniques for studying cellular automata behavior. The proof of the universality of Life is presented in detail. Among the topics covered are probabilistic CA, the relationship between CA and physics models, and a comparison between CA and neural networks.
