Common LISP : a gentle introduction to symbolic computation

This book is about learning to program in Lisp. Although widely known as the principal language of artificial intelligence research-one of the most advanced areas of computer science-Lisp is an excellent language for beginners. It is increasingly the language of choice in introductory programming courses due to its friendly, interactive environment, rich data structures, and powerful software tools that even a novice can master in short order. A highly accessible introduction to LISP, this is for inexperienced programmers and programmers new to LISP. A LISP "toolkit" in each chapter explains how to use Common LISP programming and debugging tools such as DESCRIBE, INSPECT, TRACE and STEP.
