Personal letters are primary sources, as they are firsthand accounts of experiences. Autobiographies are considered primary sources if they are written by the person who experienced the events. Diaries are also primary sources, providing insight into a person's thoughts and emotions at the time. A driver's license is not typically considered a source of information, as it is an official document for identification purposes.
