What do you mean by the material source of history?
Answer:
An artifact, journal, manuscript, diary, autobiography, document, and every other source of information that was produced at the period of study is often a primary source considered a source or evidence in the study of history as an academic field. It acts as a source of topic information.
In library science as well as other fields of education, conventional methods may be used, though various fields have very various conceptions. A primary source in journalism may be an individual with direct knowledge of a circumstance, or a text written by an individual.
