This book takes you from your first Scheme expression through advanced topics like continuations, hygienic macros, and metacircular interpreters. It explains not only how each feature works but why it exists, drawing on Scheme's history as a minimalist Lisp dialect designed by Guy Steele and Gerald Sussman at MIT in 1975. Whether you are encountering Lisp for the first time or seeking a deep reference for an existing language, this guide builds understanding progressively through complete examples, precise technical explanations, and honest discussion of trade-offs across Scheme's major standards (R5RS, R6RS, R7RS) and implementations.
