I've only read Tenth of December, and found it amazing. I am about to simultaneously read and listen to Lincoln, on a friend's suggestion: the audio version apparently helps bring all the many voices in the book to life, but I want to read along to be able to (I hope) better appreciate the language. Because Saunders is a master. Hands down.
Here, I thought I'd just provide some links to a few of his interviews and comments on the writing process et cetera, to dip into now and then (again and again). Plus a few YouTube videos, just for fun. He seems to enjoy speaking about writing and his approach to it. It's all illuminating.
