IBM Licensed Products

We (not really me) have done a horrible job of keeping and organizing our 
CD's and License packs.
Is there a resource on IBM's web site where I can use our customer number 
and/or our serial numbers and find out if we should have a license for a 
product?

I understand that I can rummage through the boxes in which these things 
have been thrown, but I was thinking there ought to be some sort of 
resource on IBM's site.
I asked IBM, but apparently they didn't understand what I was asking. They 
told me to do a DSPLICKEY. Umm, won't that only show me items I have 
installed and entered a key for??

Thanks!
