Compared to the third edition, the fourth adds more CLIPS material but removes some of the LISP and Pascal examples (which is fine). However, it still does not update the core content to reflect AI's shift toward probabilistic and data-driven methods.
❌ (start with a modern, broad AI text like Russell & Norvig). Compared to the third edition, the fourth adds
Expert Systems: Principles and Programming, Fourth Edition remains a seminal text because it refuses to be purely abstract. By pairing deep theoretical discussions of logic and knowledge representation with a comprehensive tutorial on a professional-grade tool (CLIPS), Giarratano and Riley provide the reader with everything necessary to move from a novice understanding of AI to the construction of functional, rule-based expert systems.

Expert Systems: Principles and Programming (4th ed.) remains one of the more frequently cited textbooks for anyone trying to understand rule-based AI systems, knowledge engineering, and early expert-system architectures. This column evaluates the book’s strengths, limitations, and practical usefulness so readers can decide whether it fits their needs.
