If you spend more time managing your ebook library than reading your ebooks, then this might not be for you. I have ~100 ebooks and it's "load in calibre then forget about it until I want to read" Movies took me slightly longer as while (Author, Title) is unique for books, (Title) is not.

More recently I discovered (Title, Year) is near enough to unique that I can name my rips that and Kodi is happy.
