Ok, so I went ahead and did this wiki thing. It's just an overview/example. This sort of thing is basically just fun for me to set up, so if it seems like not the best idea, totally say so. If you guys are open to it, any and all suggestions are appreciated. Then we could set up a non-sandbox version and then open it up for editing. But, again, just say the word if it should be abandoned so as to put all reference library efforts into ThoughtElf's database.
The organization of the whole thing stems from tags. I explained my vision (heh) on the home page.
Here it is:

ETA: Perhaps if we went with the wiki idea, a legitimate wiki might be better than the wetpaint thing. I think there would be more robust categorization and functionality. Though, on the other hand, there would be more intensive maintenance and issues of hosting, etc. Hard to say.
