WHAT IS A PRIMARY SOURCE?
A source that comes from a person or organization who created, participated in, or witnessed something.
Some sources are difficult to label as "primary:"
WHY USE PRIMARY SOURCES?
It is important to get as close as you can to the original event or source so you can observe and analyze without others' views clouding yours. We have all attended events and read about it later and said, "That's not how it was." It's the same with using primary sources. They help you form you own opinions and explanations. This will also greatly help you when you read secondary sources, both because you will have a clearer idea of what is being analyzed but also you can see more clearly where you agree or disagree.
WHAT IS A SECONDARY SOURCE?
A source that comments on or analyzes something, not written by someone directly involved.
Secondary sources are often based on studying primary ones. Student research papers are secondary sources.
You can often find excerpts of primary sources within secondary ones, such as a long quotation in a biography.
