Primary Sources

Sources

Primary, secondary, and tertiary sources. While primary sources are often the core of a research paper or project, researchers also depend on other types of sources to provide context, perspective, and support to analysis of primary sources. A primary source is an original material created during the time under study. Primary sources can be original documents (such as letters, speeches, diaries), creative works (such as art, novels, music and film), published materials of the times (newspapers, magazines, memoirs, etc.), institutional and government documents (treaties, laws, court cases, marriage records) or relics and artifacts.

Secondary sources describe, discuss, interpret, comment upon, analyze, evaluate, summarize, and process primary sources. A secondary source is generally one or more steps removed from the event or time period and are written or produced after the fact with the benefit of hindsight.

Often these sources are created at the time when the events or conditions are occurring, but primary sources can also include autobiographies, memoirs, and oral histories recorded later. Primary sources can be found in all of Yale’s libraries and museums as well as in online resources.

In general, a primary source is closest to the event, person, idea, or period that you are studying.

Secondary sources discuss and analyze primary sources; they're called secondary sources because they are at least one step removed from the primary source.

Primary

So, if you're writing on Emily Dickinson's 'Hope is the thing with feathers,' the poem is your primary source and a critical article discussing the poem is a secondary source.

Sources that are even further removed (e.g., because they synthesize and describe material from secondary sources) are called tertiary sources. An encyclopedia article or a Wikipedia entry would be considered tertiary sources.

Are there exceptions?
Absolutely! Sometimes what we think of as secondary sources become primary sources, depending on how you are using them. For example, if you are analyzing how literary scholars from the 1950s talked about women's literature, you would be using scholarly articles and books from that period as primary sources. Whether a source is primary or secondary depends on what you are analyzing.

If the OskiCat record mentions a 'finding aid' (an index) to a manuscript collection, you should use it to help you find what you need in the collection. If the finding aid is online there will be a link from the OskiCat record, or you can search the Online Archive of California to find it. The finding aids that are not online are near the Registration desk at the Bancroft Library.
