Primary and Secondary Sources

Primary and secondary sources are different types of information that you can use in your research.  The type of resources you will need for your projects or research papers will depend on the type of class or research that is required

Primary Sources

Primary sources are materials created at the time or specific era or event that is being researched or studied. These sources are directly related to a subject or topic by time or by a person's or material's direct involvement from the era. A primary source provides a first-hand account about a person or an event because they were written or made in the time period they are from, but can also include later recollections from a participant involved in an event (i.e. autobiographies, interviews, oral histories). The Library of Congress and National Archives provide many digitized versions of primary sources related to some of the examples found below. You may also find a few primary sources as well in the Local History room of the Library.*

Secondary Sources

Secondary sources provide useful and important background information about a topic. These sources are not written or made in the time period they are describing. Secondary sources can include books or articles published by an author or writer who makes an interpretation about an event or topic based upon other primary sources. Secondary sources include most books, encyclopedias, documentaries, websites, and academic journals. The works cited pages, footnotes, and bibliographies of secondary sources can lead you to primary sources as well. You can use the library catalog, databases, and reference books to find secondary sources. Books found in the catalog that you can check out are located downstairs in the STACKS. Reference books are located upstairs and cannot be checked out. 


  • Academic Journals/Articles                                  •  Books about the topic
  • Biographies                                                          •  Reviews
  • Textbooks                                                             •  Criticism
  • Websites                                                               •  Documentaries
  • Bibliographies                                                       •  Abstracts 
  • Interviews with Scholars or Experts                         •  Articles about the topic
  • Encyclopedias*                                                     •  Reference Books*


*Note: Reference books and encyclopedias can refer you back to primary sources. Reference books and encyclopedias can also be considered tertiary sources. Please refer to your professor on whether or not you can use these sources in your research.
