Primary Sources Research Guide - Humanities and Social Science Topics

Definition of primary source material


Primary resources are actual artifacts that have survived from past historical events, including letters, photographs, physical objects such as cooking utensils from the days of westward expansion, or articles of clothing. They provide firsthand evidence of historical events, and can represent a wide variety of formats that are generally not formally published (maps, audio/video recordings, posters, postcards, government documents, diaries, court records, census bureau data that is tabulated but not interpreted, etc.). Published materials can also be viewed as primary resource materials if they come from the period that is being discussed, and were written by somebody with firsthand experience of the event. Primary resources reflect the individual viewpoint of the participant or observer. For example, newspaper articles written by somebody who experienced the event are primary sources for political science, while a literary work is a primary source for literary criticism.

Textbooks, reviews of literature published in journals, etc. are secondary source materials in that they synthesize and typically attempt to interpret the past using available primary source materials. A secondary source might include some primary source material, such as quotes from people, photographs of an event, etc.

Note: Since the definitions of primary and secondary sources may vary according to academic discipline, you may want to ask your instructor for clarification if you are working on an assignment that requires you to use primary sources. Also keep in mind that the above definitions generally pertain to the Humanities and Social Sciences, which include such fields as English, History, Sociology, Education, and the Philosophy of Science. Very different definitions apply to the hard sciences, such as Chemistry, Biology, and Physics.

Searching the University of Illinois catalog for primary source materials


You can find whether primary source material is available on your topic through the Online Catalog.

First you'll need to find out what Library of Congress (LC) Subject Heading(s) pertain to your topic(s). LC subject headings are standardized terms developed by the Library of Congress to describe materials listed in catalogs - using them is the best way to locate all the materials on a particular subject. You will often find that the official subject heading is not necessarily a commonly used term. For instance, the LC subject heading for the Vietnam War is NOT Vietnam War but rather Vietnamese conflict, 1961-1975. There are several ways you can find out the appropriate subject headings associated with your topic, such as:

  • Ask a librarian

  • Look in the four red volumes of the Library of Congress Subject Headings book located near the 2nd floor Information Desk in the Main Library as well as other campus departmental libraries.

  • Look up the catalog record for a book that you already know about that relates to your topic, display the record in long format, and then do a subject search based on the subject headings listed by clicking on the relevant link(s).

  • Using the "quick search" feature of the online catalog, enter a term and choose "browse subject" in the right-side "Search By" menu. After you find the appropriate LC subject headings, you can apply subheadings that will locate primary source materials. Here's an example of the entire process:

Example: Finding primary source material about the Russian Revolution in the UIUC online catalog.

Find the formal LC Subject Heading for the Russian Revolution using Quick Search:

  1. Type in: Russian Revolution

  2. Select "Browse Subject" on the right side list.

  3. Click Search

  4. When viewing the results, click the "see also" button in the first column of the table to find the formal Library of Congress Subject Heading for the Russian Revolution. You should find that the official subject heading is: Soviet Union History Revolution, 1917-1921 . Copy this heading.

Next, return to the initial search screen by clicking New Search in the upper-left corner on the page. Then, click the Guided Keyword Search tab.

In the first search box, paste in the subject heading Soviet Union History Revolution, 1917-1921 and set adjacent dropdown list to (All of These) and the Search By list to (Subject Words).

In the second search box, you can then type in one or more of the specific subheadings that identify materials as primary sources. Some of these subheadings include:

  • Correspondence

  • Diaries

  • Early works to 1800

  • Interviews

  • Pamphlets

  • Periodicals

  • Personal Narratives (or just use "narratives" as demonstrated below)

  • Sources

Note: search these "as a phrase" when the subheading contains more than one word, or you can type in every one-word subheading and search all of them at once as "any word." For example:

  • Personal narratives (as a phrase) search by (subject words)

  • Diaries interviews pamphlets periodicals sources narratives (any of these) search by (subject words)

In combination with the official subject heading for the Russian Revolution (Soviet Union History Revolution, 1917-1921), using these subheadings will retrieve titles such the following, which all contain primary source materials about the Russian Revolution:

  • Witness to revolution : the Russian Revolution diary and letters of J. Butler Wright

  • Russia in war and revolution : General William V. Judson's accounts from Petrograd, 1917-1918

  • Witnesses of the Russian Revolution

Reference books that contain primary source materials


In addition to searching the University of Illinois Library catalog for primary source material on specific topics, there are many general compilations of reprinted primary source materials that appear in books which can often be found in libraries campus wide . While some of these books can be checked out, most are "non-circulating," which means you can only use them in the library. Some examples include:

  • Campaign speeches of American Presidential Candidates - 1928-1972 (History Library - non-circulating - 329.023C15)

  • Separation of powers : documents and commentary (Education Reference - non-circulating - 320.47304 Se61)

You can find some of these by searching the catalog, or ask a librarian at any University of Illinois library to assist you in identifying reference books that offer primary resource materials pertaining to your topic.

Reference books that can help you find primary source materials


  • Encyclopedias can route you to primary sources. Check with a librarian and/or search the online catalog for titles.

  • Bibliographies often offer citations to primary source materials. They can be found in libraries in the sections that start with call # 016.
