Widely shared in educational circles as a free/open resource, the book has been a primary reference for students and professionals for nearly two decades. This reflects its ongoing importance in computer science education.
Authored by Joseph C. Giarratano (a faculty member in the Computer Science Department at the University of Houston, Clear Lake, with many years of research experience with NASA) and Gary D. Riley (who was a member of the CLIPS development team while working for NASA at the Johnson Space Center from 1985 to 1996), the book comes with high authority. Since leaving NASA, Gary Riley has continued to independently develop and maintain CLIPS as public domain software. This direct involvement in the development of CLIPS ensures the book's deep authenticity and practical accuracy.

Because THETIS printed one more line:
Building an expert system requires more than just coding; it requires a structured lifecycle.
"Expert Systems: Principles and Programming, Fourth Edition" is a textbook that systematically teaches the core principles of expert systems, one of the most practical and recognizable subsets of classical AI. The book is designed to be a complete resource for understanding both the theory and practical application of expert systems. Its goal is to provide the conceptual background and programming tools needed to understand and implement expert systems.
