Mark Twain Photograph

Primary and secondary sources are different.

Primary sources are objects (stamps, maps, and photographs) and first-hand accounts (letters, journals, and diaries) created by witnesses who lived during the time of the event in history.These kinds of objects can connect you directly to the past and to those individuals who came before you.

Secondary sources are objects from a later time period and second-hand accounts by individuals who did not witness or experience the events they have recorded. Secondary sources can provide context and perspective on a historical event.
