Structure and Interpretation of Computer Programs has had a dramatic impact on computer science curricula over the past decade. This long-awaited revision contains changes throughout the text. There are new implementations of most of the major programming systems in the book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published. A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many new exercises. In addition, all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard.

Scheme - a simple, learnable dialect of LISP has emerged as a popular educational language as well as a serious tool for producing applications and system software. Programming in Scheme provides an accessible introduction to Scheme that assumes no previous programming experience and covers all the basics of the language and many advanced topics as well. It gets readers on the machine early, teaches language structure and programming technique through extended examples an exercises, and emphasizes debugging throughout.
