The book discusses several subjects of general interest, nevertheless there are only about twelve pages dedicated to Rule 110, in them it is explained the universality of this rule and some complex behaviors like the list of gliders found by Cook. In october 2002 he offers a software NKS Explorer to reproduce any of the illustrations in the book, recently offers A New Kind of Science: Notes, a book available in Internet.
The book presents the operation of a cyclic tag systems but it does not give any antecedent or reference, and it is far from explain how the parts of the system and their global operation can be constructed. Something questionable is that the book claims copyright if someone tries to reproduce such a system. In this context it is better to discuss the universality of Rule 110 and other partial results as results of Cook.
