Not for the forums, but for bicycles?

Here's what I'm looking for:

I've spent a good chunk of my online time for the weekend reading and learning a lot about bikes and cycling here at the bike forums. But is there a good place for complete, detailed explanation of all things cycling...even the basics, if you follow me.

Thanks to folks here, I know a lot about important minutia about gearing choices for my fat ass, about tire sizes for the conditions I might see, and other good stuff. But I'm still missing some basic info in a lot of areas. Examples? Handlebars...what are the reasons for all the styles and shapes? (although I did tune in to a discussion on bar width.) And I still don't know what a "hybrid" bike is, other than almost no one thinks it is a good idea.

There is a lot of other stuff I want to know, not just the examples above. Is there a "bible", either online or a book? The bike encylopedia?

Thanks
