Secondary sources are documents, recordings, or any other source of information that was created later by someone who did not experience first-hand or participate in the events or conditions under investigation. Secondary sources are one step removed from primary sources, though they often quote or otherwise use primary sources. They can cover the same topic, but add a layer of interpretation and analysis. Secondary sources are valuable for gaining an overview of a subject and understanding how it is viewed within the academic community.

Definition and Examples

A secondary source interprets and analyzes primary sources. These sources are one or more steps removed from the event. Secondary sources may have pictures, quotes, or graphics of primary sources in them. Some types of secondary sources include encyclopedias, textbooks, journal articles that comment on or analyze research, histories, criticisms, commentaries, and encyclopedia articles.

Purpose and Use

Secondary sources are used to provide additional perspectives and insights into a subject matter or to compile and synthesize information from primary sources. In research, secondary sources are often used to provide context to a research project or to enable the researcher to gain a thorough understanding of the subject.

Characteristics

Secondary sources are characterized by their analytical, interpretive, or evaluative approach to primary sources. They often synthesize a range of primary sources to provide an overview of a subject or to make an argument. Secondary sources are typically created by someone who did not have a direct experience of the event or period being discussed.

Examples in Different Fields

In history, a secondary source might be a scholarly book or article that discusses an event or era, using primary sources for evidence. In law, secondary sources could include legal commentaries or a textbook on law that interprets and discusses legal principles and cases. In science, review articles that summarize and interpret the primary literature on a specific topic are considered secondary sources.

Evaluating Secondary Sources

When using secondary sources, it is important to evaluate their reliability, bias, and relevance. Consider the author's credentials, the publication's reputation, and the date of publication. Analyzing the sources cited and the methodology used can also provide insights into the source's credibility.

Conclusion

Secondary sources play a crucial role in research and learning, providing context, analysis, and interpretation that enrich our understanding of subjects across all disciplines. They complement primary sources by offering different perspectives and bringing together a wide range of information into a coherent narrative or analysis.
