A biography is a type of writing that tells the real history of the life of a man or woman, one who made a significant contribution to the world. If that person is the author as well as the subject of the writing, it is known as an autobiography.
Primary Sources are "manuscripts, first-person diaries, oral histories, letters, interview, photographs, maps, films, sound recordings, music song sheets--fragments of history, incomplete in themselves, but when assembled, analyzed, and researched, they can provide personal insights, human drama, and deep historical understandings." Secondary sources are works that comment on primary sources.
