Final answer:
An autobiography is a creative nonfiction work where the author tells their own life story, often with a broader scope than a memoir, which focuses on specific moments or periods.
Step-by-step explanation:
The term for a work like "Background, Casually," in which the author describes his own history, is an autobiography. An autobiography is a creative nonfiction piece where the author recounts and reflects upon their own life. It is distinct from a biography, which is a narrative of a person's life written by someone else. Unlike a memoir, which focuses on specific incidences or periods, an autobiography typically covers a broader scope, often encompassing the author's entire life or significant chunks of it. In writing an autobiography, the author engages in storytelling, bringing creative elements into the true events of their life, crafting a narrative that goes beyond mere factual recounting.Memoirs, while also involving personal history, tend to concentrate on particular moments or periods and are characterized by a deep reflection on these experiences. Memoirs aim to connect emotionally with the audience, often emphasizing the thematic and emotional truths over a strict chronological account. Whether an author is sharing memories or lessons learned, both autobiographies and memoirs allow readers insights into the author's life and experiences.
