Primary sources, for historical purposes, are most often defined as eye-witness accounts of events/historical periods. Those accounts written or created at the time, not with 20/20 hindsight.
These sources reflect the point of view of a participant or observer at a particular point of time. There are a wide range of source materials available for historical research. For example: Compilations of primary sources such as a book containing many short excerpts from primary sources may not always be as useful as the original sources themselves. Source materials may have a bias or purpose which you should be aware of. For example, an article from a northern paper during the civil war will read much differently than an article from a southern paper. When reading primary sources, think about why the piece was written, when it was written, and what it tells us about the writer and the time period. The Alkek library has many databases that include primary source documents. Those are listed here Secondary sources are those written after the fact, by someone who was not a party to the original events. Scholars usually use primary sources in their research when writing secondary accounts or inturpretations of historical events. It pays to check the bibliographies of secondary sources for information about the primary sources on the topic!
