This guide will discuss the proper way to cite primary sources for research papers. First, let's review the definition and different types of primary sources.
A primary source is an information resource that is specific to its time period.
Primary sources can appear in a wide variety of formats, such as:
These materials may be found in published or unpublished form. Published primary sources are easier to find and cite, since they have some things in common with the secondary sources you are used to using.
The key to citing primary sources is to remember that every primary source is different. This is especially true of unpublished primary sources, or unique source types like speeches or artwork. Rather than closely following a formula laid out by MLA or the Chicago Manual of Style, you may need to either use a preferred citation provided by the repository that owns the original document, or construct your own citation that includes as much citation information as possible in a format that most closely matches your assigned style. This may require some critical thinking to figure out what citation information is available and how to structure it.
Note that some citation styles do have guidelines for citing manuscript collections or other primary sources. Before you begin, check to see if your assigned style includes a section like this. If it does, you may still find this guide helpful for determining how to apply the rules to your specific case. It's especially important to consult the Preferred Citations section of this guide if you accessed your primary sources through a specific repository, even if you think you can confidently construct a citation using your assigned style.
