What would be a possible approach to extracting this information, and then adding to the metadata? Would I need to first add metadata to the associated .opf file? Can I use Calibre, or will I need to use something like Visual Basic?
Look in the Help file: Command line Interface section (CLI) for what can be done that way (possibly with a BAT file)
