I think the correct answer would be primary source. It is an account of an event created by someone who took part in or witnessed the event. It is also known as original source. It is any document, manuscript, diary, autobiography, artifact, recording or any source that was made at the time being studied. Examples are interviews, archives, photographs, letters, films and scrapbooks. When the data from these primary sources are obtained from other source wherein they are being analyzed and interpreted then these sources will be called as a secondary source. Examples are articles, books, magazines, surveys, internet resources.
