1.  Lectures on Chemical Reaction Networks   These are scanned copies of written versions of lectures on chemical reaction networks given in 1979 at the Mathematics Research Center of the University of Wisconsin.  Much has happened since then, but the lectures still provide a good introduction (with proofs) to  early work. The lectures are especially recommended to mathematicians who might want to get started in reaction network theory.

2.  The Chemical Reaction Network Toolbox  This link will allow you to download an old DOS program that dates back to the 1980s but which nevertheless remains very powerful. (With only a few odd glitches, the program will run under Windows.)  Not only will it implement lots of chemical reaction network theory, it will also do many other things:  For a reaction network input, it will write out the corresponding mass-action ordinary differential equations. It will solve those differential equations numerically, plot graphs of concentration vs. time, and it will even draw phase portraits in two and three dimensions. The "official" version remains 1.02, written by Martin Feinberg.  Version 1.1 is a variant, adapted from 1.02 by Phillipp Ellison, that implements more recent developments in chemical reaction network theory, in particular those stemming from Phillipp's Ph.D. thesis.
