Thanks for your hint with the trailing space, but again, I'm not really 
a RIS specialist...

I just ran the code through the debugger.

In backend-db31.c:879 is the call to get_refdb_volume which itself calls

result = dbi_result_get_string(dbires, "refdb_volume");

This call always returns NULL.

In comparison, in backend-risx.c:864 is also the call to 
get_refdb_volume. But if this call fails, it calls get_refdb_edition in 
the else clause. This call succeeds.

So for me it seems that the RIS VL tag will be found in "refdb_edition" 
and not in "refdb_volume".
