MobileRead Forums - View Single Post - How to get rid of duplicate & different authors

While cleaning up the different ways authors are defined in an existing EPUB (like "Pieter Aspe", "P. Aspe", "Aspe P.", ... Calibre correctly inserts the "Aut" ID, but doesn't remove nor updates the existing "Author" ID. The result is that books appear multiple times in my EPUB reader(s) because they read both IDs. I'm guessing that this is because of a mixture of EPUB 2 & 3 syntax in the same file, but I can't find an easy way to REMOVE the 'wrong' ID while moving the EPUB to my device

What does work, is either remove the ID manually in content.opf within each EPUB, or convert the EPUB to EPUB (which automatically cleans up), but are these the only solutions? Both are a lot of work because I have hundreds of books to 'convert' (and would either need to 'modify one by one', or 'delete all ORIGINAL_EPUB' files manually.
