Primary source material is a key part of historical research. A primary source is a document in which an event is described by its witnesses. Some examples are: diaries, letters, speeches, letters, interviews, newspapers, autobiographies, official records including government documents, pamphlets, photographs, films, art, novels, music, furniture, clothing, buildings, and jewelry.
A secondary source interprets and analyses primary sources. Secondary sources are one step removed from the event. Some examples are: textbooks, journal articles, histories, criticism, commentaries and encyclopedias.
