i was not sure were the Sel stories are set
but i think i have a pretty good idea of the rest of the order of books if not the exact dates in relative to each other.
working backwards we know Sixth of Dusk is the latest in the timeline, even later then the Arcanum description of Drominad System. also i think that 'The Ones Above' are the same as 'Eyree', which if you missed from Secret History, they called the praises of Devotion and Domination.
Wax and Wayne/ Mistborn era 2, takes place after book 5 of StormLight and we can tell it is at least a little bit after War Breaker. i don't know how much time paced for Vivenna, Kaladin says she is about thirty but realm jumping can be weird.
Mistborn era 1 is about 300 years before era 2.
and White Sands happens before all that because of Khriss.
so of the stuff that is published in the Cosmere i think that it is White Sands < Eleventh Metal Mistborn 1,2,3+ Secret History < War Breaker < Storm Light 1,2,3< Wax and Wayne+ Allomancer Jack < Sixth of Dusk
and so that leaves only Elantris + hope and Emperor's Soul and Silence in the air.
