What is the author's style in Timequake by Kurt Vonnegut?

The author tells the story through his point of view, which regularly shifts from the first-person limited to the third-person omniscient. The third-person point of view is used to tell Kilgore Trout's experiences with the timequake, but the author injects his experiences as well via the first-person point of view. The effect is to keep Trout and the author separated until the final chapter, in which they join together for the demonstration of human awareness and its amazing speed.
