Your only chance is if you Polished the books and embedded the metadata BEFORE your corruption. In that case, you can use the Metadata editor and fetch the books copy of the metadata
In bulk mode. Do only for books that you KNOW are correct. If the book is stale or wrong, that can ruin the better entry
tick Set Metadata from book files |
Thank you for your response. I am new to Calibre. I was advised to restore the library via:
Library > Library Maintenance > Restore Database
Question Where the metadata.opf file is located? When I performed the respore, I had only 2 files in the library (
1) metadata_db_prefs_backup.json and (2) metadata.db
and after the restore, I found 3 files
(1) metadata_db_prefs_backup.json, (2) metadata.db (3) metadata_pre_restore.db
I am running Calibre on an iMac, and I have TimeMachine running all the time. (1) If
metadata.opf is located somewhere other than the library folder, I will try to restore a previous verison of it. The only other folder associated with Calibre on teh operating system that I am aware of is the configuration folder (shown in the screenshot). In that folder, I could not find a
metadata.opf

Question: I understand that Calibre is not designed for simultanuous access (therefore it's not recommneded to be hosted on a cloud service or NAS. Does that also apply to AppleTime Machine? i.e could Apply TimeMachine reuin the database?
When I looked at the metadata editor, I could not find the option
"Set Metadata from book files" .
Question: I would appreciate that you point me to it to give it a try.
