Calibre has some great features for managing metadata on Sony readers. I use the Metadata Plugboard (
Preferences - Metadata Plugboards) with the Sony special option to get authors and titles displaying exactly how I want them, i.e.
- using author_sort (LN, FN) rather than author (FN LN)
- using an abbreviated series name/series_index/title instead of plain title
I also have Calibre configured to manage my Sony metadata automatically. I'm not absolutely sure but I think this might be a pre-requisite for the Plugboard to work.
This part of the manual is relevant but may be far more detailed than you need.
If you want some specific help with simple options I will try to oblige.
On the other hand, if you are only interested in changing the author to author_sort it may be enough to go to
Preferences - Plugins - Device Interface - Sony - Customise plugin and check the relevant box.
