I've got a roughly 200-book collection in Calibre at the moment, mostly cobbled from a mix of Amazon and Kobo books. The vast majority of them are missing metadata like the ISBN or other useful info due to the import method. I'd like to go through and fix them using Calibre's "download metadata" feature, however I'm concerned that doing so will:
- Cause all of the books to fall out-of-sync with how they appear on my Kobo
- Modify the EPUBs themselves and force me to re-sync my entire collection over to all my backup devices
I did a test on one of my ebooks, and after downloading new metadata (keeping the original cover), I didn't see the EPUB itself being modified, I only saw a change to the metadata.opf in the same directory. If so, that's fine. If
not (i.e. the EPUB also gets edited), that's not a deal-breaker, I'll just need to hold off on doing this for awhile until I'm confident I've got some good backups of my library in its "pre-normalization" state.
Can anyone confirm?
Thank-you in advance!
