English:Primary and Secondary Sources
Primary and Secondary Sources
Introduction
When you study the past, you work like a detective. You look for sources: things that can give you information about people, places, ideas, and events. Some sources come directly from the time or person you are studying. Others are created later by people who explain or interpret what they found.
In this aiMOOC, you will learn how to tell the difference between primary sources and secondary sources, how to ask useful questions about them, and why strong research often uses both. You will also practice checking who created a source, when it was created, why it was created, and what it can or cannot tell you.
What Is a Source?
A source is anything that gives you information about a topic. A source can be a diary, letter, photograph, map, object, recording, newspaper, book, website, interview, or video. Researchers do not simply collect sources. They ask questions about each source and compare it with other evidence.
One helpful question is: How close is this source to the person, event, or time I am studying? That question helps you decide whether a source is primary or secondary.
Primary Sources
A primary source is original evidence connected closely to the topic you are studying. In history, it is often a document, object, image, or recording created during the time being studied or by someone who took part in the event.
Examples include a diary written by a person who was there, a photograph taken at the time, a letter sent during an event, a speech recording, an old map, an official record, an artifact, or an interview with a person describing something they experienced.
The image below shows a 1903 diary page connected with the Wright brothers and the first successful airplane flight. A diary like this can help researchers learn what a person recorded at the time.
A newspaper can also be a primary source when you are studying the time in which it was published. For example, an old newspaper can show what information readers received, which words writers used, and what issues seemed important then.
Photographs can preserve details about clothing, buildings, tools, faces, and surroundings. However, a photograph shows only one moment and one point of view. You still need to ask who took it, why it was taken, what is outside the frame, and whether a caption was added later.
Oral history can also provide firsthand evidence when people describe events they personally experienced. Recordings are especially useful because they can preserve voices, wording, pauses, and emotion.
Questions to Ask About a Primary Source
When you examine a primary source, ask: Who made it? When was it made? Where was it made? What was happening at the time? Who was meant to see or hear it? Why was it created? What details do I notice? What questions does it leave unanswered?
A primary source is valuable because it can bring you close to a time, person, or event. But it is not automatically complete or perfectly accurate. A person may forget details, a photographer may choose one scene instead of another, and a newspaper may tell only part of a story.
Secondary Sources
A secondary source explains, analyzes, compares, or interprets information from primary sources and often from other secondary sources. It is often created after the event being discussed by someone who was not directly taking part in that event.
Examples include many history books, biographies, documentaries, encyclopedia articles, museum explanations, and school textbooks. A good secondary source should show where its information came from so that readers can check the evidence.
Secondary sources are useful because they can bring together information from many places. An author can compare several letters, photographs, records, and interviews, then explain patterns that may be hard to notice in only one primary source.
Source Type Depends on the Research Question
The same item can sometimes be primary for one research question and secondary for another. Imagine a history textbook published in 1995. If you are researching ancient Egypt, the textbook is a secondary source because it explains a much older time. If you are researching how students learned history in the 1990s, that same textbook can become a primary source because it is direct evidence from the time you are studying.
This means you should not label a source only by its shape. A book is not always secondary, and a photograph is not always primary. The research question matters.
Comparing Sources
Strong researchers use more than one source. One source may contain a mistake, leave something out, or show only one person's point of view. Comparing sources is called corroboration. When two or more independent sources support the same idea, your conclusion may become stronger.
You can also notice disagreements. A diary may describe an event one way, while a newspaper reports it differently. A later historian may explain why those accounts do not match. Disagreement does not mean you should give up. It gives you a new question to investigate.
A Simple Source Detective Checklist
Creator: Who made the source, and what might that person know?
Time: When was the source created compared with the event?
Purpose: Was it made to inform, persuade, record, entertain, sell, or remember?
Audience: Who was expected to read, see, or hear it?
Evidence: What facts, details, or clues does it contain?
Limits: What can this source not tell you?
Comparison: What other source could confirm, challenge, or add to it?
Interactive Tasks
Quiz: Test Your Knowledge
Which description best fits a primary source? (Original evidence closely connected to the topic) (!A summary copied from several websites) (!A later explanation of an old event) (!A list of modern book recommendations)
Which item is most likely a primary source for a study of a school day today? (A student's diary entry written today) (!A history book about schools long ago) (!An encyclopedia article about education) (!A documentary made years later)
Which item is most likely a secondary source about an event from 1903? (A modern history book explaining the event) (!A diary entry written in 1903) (!A photograph taken during the event) (!A letter written by a witness in 1903)
Why should you ask who created a source? (To understand the creator's knowledge and point of view) (!To decide whether the paper looks old) (!To make every source agree) (!To avoid comparing evidence)
What does corroboration mean? (Comparing sources to see how their evidence fits together) (!Choosing the longest source) (!Using only one eyewitness) (!Ignoring sources that disagree)
Why can a photograph be incomplete evidence? (It shows only one moment and point of view) (!It can never show real people) (!It is always created much later) (!It cannot contain useful details)
What is one strength of a secondary source? (It can combine and explain evidence from many sources) (!It is always written by an eyewitness) (!It can never contain an interpretation) (!It automatically proves every claim)
Why can the same item be primary in one project and secondary in another? (Its role depends on the question being studied) (!Its paper changes over time) (!Only teachers decide its type) (!Its title determines its type forever)
Which question best helps you examine a source's purpose? (Why was this source created) (!How many letters are in its title) (!Is the source my favorite) (!Can I finish reading it quickly)
What should you do when two sources disagree? (Compare their evidence and investigate the difference) (!Throw both sources away) (!Choose the source with more pictures) (!Assume the newest source is always right)
