Guide to finding digital collections of 19th - early 20th century primary sources

Primary Sources vs. Secondary Sources

What are primary sources?

Primary sources are documents (or other kinds of materials) that were created in the past that can be used by researchers in the present to gain insight into a specific time period. Primary sources provide ideas and evidence about events in the past. Scholars use the evidence found in primary sources to draw conclusions and construct narratives about the past.

In art history, primary sources might include:

  • letters or records of sales between artists, patrons, dealers, friends, etc.
  • exhibition reviews or eyewitness accounts of events (reviews of the 1913 Armory Show, photos of World's Fairs)
  • ephemera (items not meant to be kept long-term): ticket stubs, exhibit pamphlets, t-shirts, playbills, tote bags, etc.

Primary sources can also include the original object of study, such as original paintings or photographs, historic fashion or furniture, and other objects and remnants of material culture.

What are secondary sources?

Secondary sources are published works that present arguments and conclusions about events in the past based on primary source (or archival) research. Types of secondary sources include: research/scholarly articles, textbooks, magazine articles, histories, criticisms, commentaries, and encyclopedias.

How do I search for primary sources?

See the tab "Explore Primary Source Collections" for a selection of digitized sources available through Mason or other public/open sources.

  • Digital collections: Digital collections are often organized by topic, or allow you to search by keyword or subject headings (i.e. special terms that are used to label what a source is about, like "Labor laws" or "Civil Rights Movement"). Digitized archival collections may also be organized using a finding aid.
  • Library catalogs: Some primary sources are reproduced/republished into books. To find these in a library, try searching for your keywords and one of these subject headings for primary sources:
    --correspondence; --description and travel; --interviews; --maps; --narratives; --collections; sources; --pictorial works; --diaries; --biography, --quotations; --discovery and exploration

  • What do you know about this organization?
  • What do you know about the historical context of the source?
  • How does the source creator fit into this historical context? What was his or her role?
  • Why was this source created?
  • What kinds of factual information does it provide?
  • What is conveyed, but not necessarily intentionally?
  • What is not conveyed in this source? What isn't being said?
