Comment 14 for bug 1367943

About sorting by different authors: You could make the main Author field aware of its order, (if it is not currently): A & B & C not being the same as B & A & C. No need for a complementary Author sort field. I mean, selecting the primary or secondary author is a completely different issue than how each author is itself sorted against other authors.

But I agree that maybe different publishers, editions, languages, whatever, could use different ways of sorting, (or even NAMING), the very same author. So a per-book setting could be desirable although it can result really, really messy...

Because of your last replies I suppose, (I'll test later nevertheless), that the Calibre main table view is then sorted by the per-book author sort value, not by the global author sort one. Am I right? I mean if I set "Rivera de la Cruz, Marta" in one book but "Cruz, Marta Rivera de la" in another one, when I sort by author both books are going to be quite separated... (As I said a really, really messy issue).

If this situation is what happens (or even the contrary) I'd suggest a possible new enhancement for Calibre: the possibility to switch between both sources in when sorting by author the Calibre main table view. If you ticked/unticked it both books would be sorted either together or separated...
