Hi, I have my Calibre library divided into several Libraries (e.g. General Fiction, Juvenile, SciFi, etc.). This library is stored on my Qnap NAS and occupies some 46+GB! Recently my General Fiction folder's metadata.db became corrupted, probably because I was running critically low on RAM with a lot of apps (incl. Calibre) open. I am running OS X Yosemite (latest). This has been fixed with the addition of an additional 16GB of RAM over and above the Apple standard 8GB (new total 24GB).

All the folders with the books and their metadata are there, Calibre | General Fiction | one folder per book (nested under author). I was wondering if there was a way to 're-add' my entire library without creating obscene numbers of duplicates? I see that Calibre warns about duplicates and doesn't appear to add them. Is this true?

If it is, am I safe in simply telling Calibre to re-add the contents of my General Fiction library and it will just add the missing books and their metadata from the relevant folders?

As there are about 7,000 books it would be a monumental task to recrete the metadata for them all!

Thanks for a very informative forum. I have benefited from your collective wisdom on several occasions.
