@jaror Let me be honest about the real motivation for the book. As I've given talks about it, I've been describing it as my "greatest hits album": reworked and updated material from some favourites among my own papers, plus a few "cover versions" of papers by others that I wish I had written myself.
@jaror In particular, I promised myself No New Research. I tried to do that on my previous sabbatical, seven years ago, and got sidetracked by https://doi.org/10.1145/3236779. And on the sabbatical before that, another seven years earlier, and got sidetracked by https://doi.org/10.1145/2034773.2034777. I'm proud of both those papers, but they didn't get the book written!
@chrisamaphone @jer_gib @jaror This is making me think that people should retract papers from Springer and republish then with (AUTHOR's version) appended to the title.
