"The Handbook of Artificial Intelligence" Vol. I (1981), edited by Avron Barr and Edward Feigenbaum, is one of the first systematic attempts to map AI as a discipline. Search, knowledge representation, natural language, inference, all pre-connectionist, entirely symbolic. A snapshot of what the field knew how to formulate before it knew how to scale. Still worth reading today because it shows how much of the field is older than it looks.
