Another option is to just replace their whole calibre library folder with yours, especially if you have all the books that they have added to their library. You would not need to do any merging, just replace their library with yours. You would have to make sure that you copied all files and folders, including the metadata file.
If they have books that they have added to their library, that you don't have, or they have some custom fields that they want to keep, then this won't work.
