Primary sources provide first-hand information about an event or phenomenon. In contrast, secondary sources offer second-hand information and analysis, drawing from primary sources.
What is a Primary Source?
A historical document or artifact created during a particular period of time... primary sources provide researchers with information directly from the time period being studied.
