Adding the series in the kobo reader necessitates a specific process.
Even with the series infos correctly set in the epub/kepub metadata, the reader does not import it from side-loaded books.
I’m using Calibre to manage my ebooks and load them on my Libra 2, but I hope it will work with books side-loaded differently.
You will need to have the ebooks in Calibre, and the plugin
Kobo Touch Extended Driver.
In the plugin settings, in the "Metadata, on device & advanced" tab, you need to check "Update metadata on the device" and "Set series information" if it’s not already set by the default config (I hope that these are the only settings to set, my current working config is a lot of years of tinkering, sometimes just trying until it works).
I’m not sure how Calibre matches books on the device and in its library, so it might not detected that these are the same books.
So the process is:
- add the books to your device and let them load by the reader by disconnecting it from the computer
- re-connect the reader to the computer
- in Calibre, the device must be detected and the books marked automatically as on the device in a column that is only shown when a device is connected
- the plugin will update the device database with the series info automatically
- eject/disconnect the device, and now, your books will have the series displayed in the reader.
It’s working for me with my device and my current Calibre config, but the process may corrupt your device database as it’s modifying it. So don’t do it if your not ready to potentially loose all reading states, notes, etc.
