WLL 560: Principles of Scholarly Research: Primary Sources in Books
What is a primary source?
Primary sources enable the historical researcher to get as close as possible to what actually happened during an historical event or time period. A primary source reflects the individual viewpoint of a participant or observer. Here are some examples of primary sources:
- Items that describe events where the author is a participant or observer, such as diaries, letters, memos, journals, speeches, and interviews. Example: Diary of Charles Rumley from St. Louis to Portland, 1862
- Photographs, audio and video recordings, and other electronic records that record an event. Example: Oregon Politics Radio Disc Collection [sound recording], 1938-1958
- Records collected by government agencies such as birth and death records, marriage records, voting tallies, land deeds, and census data. Example: 15th census, population, 1930. Oregon
- Records created by organizations or agencies, such as reports, minutes of meetings, and bylaws. Example: The dawn of British trade to the East Indies as recorded in the Court Minutes of the East India Company, 1599-1603
- Memoirs and autobiographies. Example: Autobiography of Samuel L. Campbell, 1824-1902 : frontiersman and Oregon pioneer : together with his summary of the Whitman Massacre.
- Material published at the time of an event, such as books, newspapers and magazine and journal articles. These are distinguished from secondary sources because they are contemporary. Example: Jones, W. F. D. "An Oregonian Poet Hermit." Overland Monthly and Out West Magazine, V. 25, issue 148, April 1895, pp. 75-378.
- Data collected by researchers, such as field notes, results of experiments, and measurements. Example: Climatological data. Oregon.

What is a subject heading?
Subject headings are a formalized way of of searching library catalogs. The right subect heading can help you get to information more quickly.

You could search the library catalog for all those keywords. Or, use one subject heading to find all of the library's materials about the the American Revolutionary War:

Searching for primary source materials by author
