Getting started in electronic publishing. Best way to distribute notebooks?

[bkinney (Bill Kinney)]

I’m interested in learning how to get started in electronic publishing in Mathematica. I’m creating supplements for my differential equations course to teach the relevant mathematics and Mathematica coding simultaneously. I’d like to be able to distribute these notebooks to a wider audience, but am unsure the best way to proceed. The Mathematica supplement for the first section is attached for your interest (note: it’s longer than most of the notebooks will be because I have a lot of content related to list operations that won’t typically be there).
