Kobo Libra 2: PDF metadata is incorrect

Phssthpok · 05-06-2026, 12:30 PM

I have just decided to store some PDF books on my Libra 2, but when I upload them from Calibre the metadata is being taken from somewhere else. I've checked the Calibre metadata and it's correct, but I get titles like "Author - Title" by "Unknown author", or 0123456789.pdf by Unknown Author, or the author is called "Doe, John (1885-1923)" (with quotes) instead of John Doe.

Where is it getting this from, and what can I do about it?

The Kobo seems to be ignoring the Calibre metadata in favour of the embedded metadata in the PDF file. I have found a PDF metadata editor which seems to do the trick -- except that I can't figure out how to include series info. Any ideas?

OK, the solution I found was to delete all the metadata, copy the books to the Kobo, disconnect and wait for the content to refresh. then connect again, wait for Calibre to load the book list, and disconnect again.
