 the number in the containing Folder is the books {ID} if that helps |
Not what I'm looking for. The books are already in the library, I'm confident they are the same book (bitwise identical), but I want to merge the the metadata.
I'm thinking of a command something like
Code:
calibredb merge id1 id2 id3
If I've got a '#notes' custom column, and the three titles with IDs id1, id2, id3 have #notes values of 'Note 1', 'Note 2', and 'Note 3', when I merge via the GUI I get a #notes value of 'Notes1\n\nNotes2\n\nNotes 3'. Taglike fields are similarly aggregated and the union stored in the result.
