This is a text which covers the basic elements of writing AutoLISP code. It suffers from trying to start at too low a level (explaining, for example, how to use a computer) and pitches too slowly. The authors perhaps have not read Abelson and Sussman's "Structure and Interpretation of Computer Programs". Although the advertising blurb claims that it covers all AutoLISP functions, it lacks in clarity of presentation, and has no function-by-function alphabetized reference listing. Given the paucity of AutoLISP texts, this is an acceptable book. Were there more sophisitcated texts available, it would be one to avoid.
