Primary sources are the evidence of history. They are the first-hand accounts of an event or period of time created by participants or observers. There are many kinds of primary sources including texts (letters, diaries, government reports, newspaper accounts, novels, autobiographies), images (photographs, paintings, advertisements, posters), artifacts (buildings, clothing, sculpture, coins) and audio/visual (songs, oral history interviews, films).
See the History Research Guide for information on how to find specific types of primary sources.
Look on the institution's website for guidelines on visiting and using the collection. Libraries and archives often have a "prepare for your visit" section and email or chat help services.
