A author's story about himself is a/an

An author's story about himself is an autobiography. An autobiography is a written account of a person's life, written by that person. It is a first-person narrative that describes the author's life experiences, including significant events, people, and places. Autobiographies are often used to share personal experiences, emotions, and reflections, and provide readers with insight into the author's life and perspective. Unlike biographies, which are written by someone else about a person, an autobiography is written by the person themselves. Therefore, an author's story about himself is an autobiography.
