These are the standard columns I exclude from Metadata Copy/Paste -- 'authors', 'author_sort', 'title', 'title_sort', 'pubdate', 'timestamp', 'cover'. I also exclude some custom columns, but they're specific to my Media and Journals libraries.
In this thread ==>>
how to write enable calibredb on mac osx the OP mentions the
LazyLibrarian program. It may be of interest to you - caveat, I think it is only available for Linux or MacOS.
I keep Author information in Evernote notes, see ==>>
Calibre and Evernote. But, I
don't copy any data from my Author notes into calibre library metadata columns. If an Author has an Evernote protocol link (evernote://blah-blah) in the Link field, when I click on Author name in Book Details that Author's Note is popped by Evernote.
