The Scheme programming language 4th ed.

Scheme is a general purpose programming language descended from Algol and Lisp. Because it is conceptually clean and simple, it is an easy language to learn. At the same time, it is a powerful language, and full mastery of its power requires careful study and practice.

Scheme is widely used in computing education and research, as well as for a broad spectrum of industrial applications ranging from graphical user interfaces and language compilers to virtual reality engines, web navigators, and enterprise computing solutions.

This revised edition of The Scheme Programming Language provides an introduction to the language for readers with some programming experience. Beginning with a gentle introduction for novice Scheme programmers, it leads the reader through a series of progressively more difficult examples that introduce each of the major features of the language. Advanced concepts and features are thoroughly covered with examples and exercises appropriate even for more experienced programmers.
