A few years ago, I made copies of my Library. I don't know why I did it (apart from being an idiot). I'm pretty sure I didn't use any features in Calibre to copy them and rather just...copy & pasted them into their own directory(s).

Anyway, now I'm looking at my "One True Library" and I suspect...it isn't. At all.

So, how best can I import (?) the copies into my "real" library without duplicating or over writing metadata (which I have painstakingly updated. Sigh)?

Thanks.

Edited to add: Just looking into those copied directories...some books that I've updated data for in the "Real" library has been updated in the copied ones. Whoa. I have no idea what this will mean for any merging.
