I've got over 20,000 books. I'm looking for a way to add tags without having to do any work…. … … Seriously, though, it would be a great help if there were any existing tags lists out there anywhere that might help reduce the load a bit. I'd also appreciate any suggestions on how to even further lighten the load, such as perhaps some library search terms that might help gather groups of books where each book in the group would be a candidate for the same tag, for example, "all books which are to be tagged exegetical".
