While primary sources originate from the time period in question, secondary sources are one step further removed from the historical event. Secondary sources interpret or analyze one or more primary sources or other secondary sources. They will include a Works Cited or References page where they cite the other sources that they have used in their research. In other words, secondary sources look at the past through the lenses of other sources, as opposed to primary sources which are expressions of first-hand experiences or thoughts. Secondary sources synthesize information and ideas from multiple authors, sources, and time periods to reveal something new, much like how looking at something through a film lens filter changes the colors you can see. Layering these lenses adds depth and nuance to a research topic in fresh and exciting ways!
