Not sure if this is the right place for this but here goes.

Somewhere along the line in my latest writing escapade I have included a dragon. I rarely if ever include such mystical creatures into my stories and although I know a lot about the basic dragon lore and such I was looking for information that may have been left out of the Dragonology book (I'm kidding, that's not the resource I read, lol, but it is a fun book).

I know that there are people who know quite a bit about them so if anyone can help me out or lead me to a website/book etc that is a good center for info, I'd greatly appreciate it.

I know very little on this subject, probably not much more than what you've already found through your research.  I tried to find the links to sites with on-line books, that I've found very informative through the past, but couldn't find the ones I wanted.  If come across them I will let you know.
Here's one, you might try changing the search subject I just typed in dra .
