I recently managed to recover off of an old, crashed hard drive most of my old Calibre library. It appears that the folder structure and format files are (mainly) intact, but the database is hopelessly corrupted.

Both my old library and my new one contain about 1200 books, with an overlap of (very roughly) 800. I would like to import the old library into the new one without having to manually do it folder by folder. Ideally the import process would not copy duplicates, but I'm willing to do de-duplicating as a separate step if need be.

If never tried to import anything this complicated, and I am afraid of messing up my current library in the process. Can anyone tell me a safe, and not too laborious, way of achieving this?

Thanks! Beanxx
