Secondary Sources

Secondary sources are material that has taken a primary source and summarized it, analyzed it, combined it, rephrased it and interpreted it.  It is at least one step removed from the event or phenomenon under review.  A secondary source may try to persuade or argue a position.  Much of what you find as sources will be secondary.

Examples:  Reports, summaries, textbooks, speeches, articles, encyclopedias and dictionaries

          Book:  "Civil War Dictionary"  Book "Retracing the Past"

Can a source be both primary and secondary at the same time?

From one vantage point, books are the classic secondary source:  scholars use primary source materials such as letters and diaries to write books, which are in turn secondary sources. Books can also be a rich source of primary source material.  In some instances, as in the case of published memoirs, autobiographies, and published documents, it is easy to determine when a book functions as a primary source.  But even secondary source materials can function as primary sources. 

Book:  Eminent Victorians

Take, for instance, Lytton Strachey’s famous history of nineteenth century England, Eminent Victorians, first published in 1918.  On the one hand, Eminent Victorians is a secondary source, a history of English society and culture in the 1800s based on Strachey’s research and analysis of primary sources.  On the other hand, a present-day scholar could treat Eminent Victorians itself as a primary source, using it to analyze the mores and attitudes of Lytton Strachey and the early twentieth century English intelligentsia of which he was a part.
