Iain M. Banks.
TSOTA is collection of short sci fi stores from Banks. Several of them take place in the Culture universe.
Some of them don't. A few of them end with very weird twists. The titular story—"The State of the Art" is a prequel of sorts of the novel "Use of Weapons" There are a two other Culture stories in the book, though they are disconnected from the other Culture novels. This seems to confirms my theory that when Banks wants to write a sci-fi story, he uses "The Culture" as background. So he doesn't have to invite a whole new universe. He doesn't write about the Culture because he has a grand end to end vision.
