I know it's possible to add empty books, and use empty books to catalogue hard copies in a library.

Not everything has an isbn, but are there tools to input metadata based on isbn?

I would still have to add some of my own metadata, but not nearly as much.

I have severe rsi, so I can't type everything in, without tools like the above, and I have coordination and sensory issues, so can't use phone/tablet apps to scan everything in. I can't escape painfully loud construction noise, so can't use Dragon or Enhanced Dictation either, during the construction, and don't want to waste the moments of peace, during the breaks. I don't think Dragon or Enhanced Dictation would work for data entry anyway, because they can't recognize isolated words.
