The April 1990 IEEE Computer magazine has an article called
"Fundamentals of Bar Code Information Theory" which goes into
great detail including mathematical analysis of information
densities, noise and distortion errors, etc.  This is an
article on the underlying theories rather than a tutorial
containing coder/decoder algorithms.  To be honest, I was
looking for "Bar Codes Made Simple" when I first read the
article, but it was interesting enough that I waded through
it, anyway.
