[78-L] HMV catalog/archive?

[Malcolm Rockwell]

Is there a website for what HMV has/had in their archive? If not is 
there an online catalogue of issued British HMV 78s available - like a 
British equivalent to Ty's "Online Discographical Project"?
I thought I had saved an address a few years ago but cannot locate it. 
Possibly it didn't come along when I migrated my bookmarks from my old 
computer to the new one.
Thanks,
Mal
