I am not a discographher - I support discographers. So, I can't speak with experience on the best way to do this. But, you're not the first one to tell me that they'll "eventually enter the data into BRIAN." I always wonder, why not use BRIAN while doing the research, not after. When I first developed BRIAN, that was the primary goal - to assist the research, not make the reports. BRIAN does a lot of things to prevent errors and assist in cross checking information. Why not use that? Unless you don't have a laptop and are tied to a desktop computer, I can't see entering data twice.
Again, I'm looking from a distance...
