I think I see what you've got in mind, and I bet a blogging environment could get you quite close.

I've seen lots of bloggers break longer pieces into separate entries, or chapters, if you will. Subsequent chapters would all begin with a link back to chapter 1, as it's entirely likely that web searches would turn up results from all over your blog. You could, in fact, have a table of links in each part that acts as a table of contents.

The thing about a garden-variety, do-it-yourself website is that you might find it's not as "plugged-in" or connected as is a dedicated blogging site. It also may lack some of the writing, editing and publishing tools that are standard fare for blogging sites. You can build all this stuff into a website if you wish, but aside from it being an interesting academic challenge, what would be the point?

OTOH, I'm talking out a my butt here, as they say. Robert knows *way* more about this than I do, and it sounds like Tom has considerable experience with blogging as well.
