No I mean, I had links in that page that linked to my public dropbox folder. I'm not talking about files we suspected existed but weren't sure about; there was a link that I had put in to files that, looking in my dropbox, do not exist. I can't imagine doing that on purpose, but I also can't imagine why I can't find links to them now. In at least one case (CRD for 4 May 2004), there is a CRD for 5 April, so I imagine it's a matter of there being a 04/05 05/04 mixup, but I have no explanation for the others.
