I would say various Pocket Books TOS novels from the eighties, and everything in the "John Byrne Collection."
Since my personal headcanon basically only includes the 23rd century, it's just fine if novels and comics disregard TNG and the other spinoffs, which Byrne does unashamedly in his TOS work.
