If you mean, like what EQ2Players tracks, there is nothing like that in EQPlayers that I know of. I think Magelo has an item discoveries tracker, if you're a premium member and use their in-game tracker, but of course it doesn't cover everyone.
Similarly, here, use of Lucy will track the first person to upload an item, but again, not everyone uses Lucy. As far as I know there's no on-site search for Lucy submitted by, but I generally, just use advanced google search and limit the search to
https://everquest.allakhazam.com/db/item.html?item= and my Lucy name "Yther Ore". In this way, you get the Lucy submitted stuff, but you'll also get any item you've updated as well, and I get items I have posted on, since my Lucy anme is the same as posting signature.
There is still one item (a 65ish dagger, appears to be from DoDh - TSS era), that I had submitted, but I could neer find the link in my logs to see where I got the link from or where it dropped.
Well anyway, I hope this helped some.
Yther Ore.
