Ok gang, I'm still confused on one point. I get the whole ISBN/ASIN concept. But I have my preference to "read metadata from file contents rather than file name" when I add books. So when I add an EPUB that I download from the library, why is the ISBN pulled for the DTB not the ebook version??? Example:
Brazen Virtue - ISBN 9780553897005 vs 0553897004(i get this from Goodreads & manually update). FYI: the Extract ISBN plugin changes it back to the original value.
