What is the author's style in Notes of a Dirty Old Man by Charles Bukowski?

The structure of the book is one of an almost continuous stream of thought, during which, Bukowski's perspective changes from first person to third person several times. In his first person stories, Bukowski often tells of his own personal experiences mixed with some level of fantasy. On occasion, however, Bukowski will write in the third person, indicating someone other than himself is the main participant. Even in these stories, however, readers are given a sense that the third person perspective is simply a cover for more humiliating periods of Bukowski's own life.
