This my work on the problems from Simply Scheme: Introducing Computer Science (2ND ed.). The book teaches functional programming using a light abstraction layer of standard Scheme and is meant as preparation for SICP.

My work on the problems from Essential Lisp (Anderson, Corbett, and Reiser). The book describes mid 80s Lisp but this work was done in Scheme.

A more accessible copy of the sample code and abstraction layer for Simply Scheme: Introducing Computer Science (2ND ed.). This book teaches functional programming using Scheme and was intended to be a precursor to SICP.

A more accessible copy of the code for SICP 2E. This is the Scheme version, not the heathen Javascript version ;)
