Primary
& Secondary Sources
A primary
source is first-hand information from a person who witnessed or
participated in an event. It may also be scientific data, statistics,
or an official transcript of a government proceeding. A secondary
source is a description by a person usually not present at the event
and relying on primary source documents for information. Secondary sources
usually analyze and interpret.
The distinctions
between primary and secondary sources can be ambiguous. An individual
document may be a primary source in one context and a secondary source
in another. Time is a defining element. For example, a recent newspaper
article is not usually a primary source; but a newspaper article from
the 1860's may be a primary source for civil war research.

To locate
primary sources in the library
- Do background reading
in a specialized encyclopedia for your place/time period to locate
key names, vocabulary or events.
- Search the Library
Catalog by Keyword, using a primary source format word as one term
and an event or person as another term. Truncating the format word
is helpful to obtain both singular and plural:
letter* and Lincoln
diar* and Civil War
-
Find
primary sources in the footnotes and bibliographies of secondary
source books and articles.
-
Browse
the shelves in your subject area.
-
To
locate research data and reports in the sciences and social sciences,
use one of the subject specific databases or indexes for that discipline.
