I've looked before, though not extensively, and haven't found it. It looks like they now lock down parts of thier site to players registered via Arena so it is possible that might be located in those sections.
Recent norms can be found here though:

Actually, in looking at that more closely, that may actually be it. You can click on any of the names in the list and it will show their norm history. Never noticed that before.
Also, it is possible a player had older norms that expired; see FIDE regulation 1.55 -- https://www.fide.com/fide/handbook.html?id=174&view=article
Hmmm... That's a little odd. That could be it, but, if it is, then it would suggest that players like IM Danny Kopec, IM Jay Bonin, IM Jeremy Silman, and IM Mark Esserman have zero GM norms. That's a little hard to believe, but just a little, because I know it is difficult to acquire them. Nonetheless, I thought Silman had one, for sure.
It's possible they had them in the past and they didn't register them by the listed regulation above; so potentially anything prior to July 1st, 2005.
It is also possible that the site isn't 100% correct 
More details about that: http://www.fide.com/component/content/article/1-fide-news/7202-title-norms-deadline-extended-to-31-july-2013.html
If they didn't feel they were ever going get another norm, they might not have registered them or may not have known about it prior to the deadline.
I'm interested in finding how many title norms certain players have, but I can't find it on any FIDE pages, and I don't think USCF pages have them, since the USCF has its own bizarre titles (Senior Master, etc.). For example, I am interested in whether Jay Bonin has any GM norms. Is there any where I could find such information pertaining to title norms?
