Is there a catalog of HDCD recordings?

Is anyone aware of a listing or catalog of recordings that utilize the HDCD process? I have been rather surprised by the fact that some recordings give no indication that they are HDCD on the cd's external packaging. Thanks, Will.
hdcd.con, as indicated by wirehead. I just don't think that they've updated in a while. From what I've heard, there are other variations almost like hdcd that will cause your player to indicate it has and hdcd disk. Do to the laws, they can't print on thier disk "hdcd". But they still sound good.
