Programming in Prolog by W.F. Clocksin is a landmark introduction to logic programming and the Prolog language, a cornerstone of early artificial intelligence research and symbolic computation. This concise yet thorough text walks readers through Prolog's declarative structure, recursion, pattern matching, and its distinctive approach to problem-solving via logical inference. Widely adopted in both academic and professional settings, it shaped how generations of programmers approached non-procedural languages and remains a key reference for those studying AI history or early computing methodologies. This 1987 printing represents an increasingly collectible edition from the formative era of modern programming and artificial intelligence, offering both instructional value and historical significance.

The paperback is in very good condition, showing only the slightest shelf wear. The binding remains tight, and all pages are clean and unmarked. A well-preserved and highly collectible copy, ideal for both use and display in any computing or AI-focused collection.
