Hi Federico, and others,
Are most of the case you find perfect duplicates like
these?
I'm still running the comparison, but I made a first list of ~500
duplicate works available here:

It would be very useful to get some feedback on that. Looking through
some of those will give an idea of the kind of "duplicates" we find.
Sincerely,
Jonas
