So I just added 100s of new titles to my kindle thru calibre and edited the metadata all nicely, took hours and hours. Just found out my kindle has the authors listed alphabetically by first name whereas calibre has them the more sensible way by surname.
I tried to follow the "preferences" guide in calibre but it is way too complicated for me.
Please, someone tell me there is an easy way to correct this on my kindle.
