Besides the Variants that Kiwidude pointed out.
I hate 'shotgun' tagging
All Science fiction is NOT Fantasy or Fantasy and Science fiction.
Science Fiction is: Du-oh!, Fiction
so why do I need a Fiction tag
on that book.
I will give tagging story locale a break, but Author locale? at the book level?
(Does Lisanne Norman
moving to the USA stop her from being a English Author? USA authors moving to Ireland, stop being American Authors?)
As it is, I have 112 'Tags' and 61 'User tags' (coding notes, comments that don't make it into the book on export) for 2500 entries (some are place holders for DT books)
Tags fall into the same area as Firstname Lastname or Lastname, Firstname
