Biography is the description of the particular facts of a person's life, and may contain photos that testify to the events. It is a document that shows the life trajectory of a person, with accurate data, including names, places and dates of the main events. The autobiography is also a biography, but written by the person the biography is talking about.
For this reason, we can conclude that if you want to have a truer view of someone's life, you should read a variety of biographies. This is because each writer can complement the biography of the other.
